The saying the closer a planet is to the sun, the shorter the rotation period is true

The closer you are to the Sun, the shorter the orbital period, but the rotation period is often the opposite, and the rotation period of planets close to the Sun is slow, although not the closer you are, but generally slower.

Because when it is closer to the Sun, the huge gravitational pull of the Sun will have a tidal effect on the mantle material inside the planet, thereby slowing down the rotation of the planet, and eventually making the rotation period of the planet infinitely close to the orbital period. For example, Mercury has an orbital period of 58 Earth days and an orbital period of 87 Earth days. Venus's rotation period is 243 Earth days and its orbital period is 224 Earth days.

It will not be like the earth, which is farther away from the sun, with a huge contrast of rotating by one day and revolutionizing for 365 years. The tidal forces of the Earth also seriously affect the rotation of the Moon, which now coincides with the 27-day orbital period. Similar examples include Jupiter and its moon Io, as well as Saturn's nearby Enceladus.

Their rotation period is very close to the revolution period.

However, the closer you get to the Sun, the shorter the planet's orbital period becomes. Because when you are closer to the sun, not only is the orbital path shorter, but also the orbital speed is faster. Mercury's orbital speed reaches kilometers per second, which is much faster than Earth's 30 kilometers per second.

Neptune, the farthest planet from the Sun, orbits at a speed of only kilometers per second, and its path is hundreds of times farther than that of Mercury, so it takes 164 years for Neptune to orbit one revolution.

The orbit of any celestial body is the same, the speed of the star is directly related to the distance, and the speed of the planet in the elliptical orbit will change with the constant change of distance from the sun. Details can be found in "Kepler's Law".

Obviously not! Encyclopedia - Rotation period data:

Mercury days (58 days).

Venus day (reverse rotation).

Earth days ( hours 86,164 seconds).

Moon day (synchronous).

Mars days (hours).

Jupiter day (9 hours 55 minutes seconds).

Saturn day (10 hours 39 minutes seconds).

Uranus day (17 hours 14 minutes seconds, reverse rotation) Neptune days (16 hours 6 minutes 00 seconds).

There are many factors involved in the formation of the rotation of the planet of Pluto d (6 days 9 hours min, reverse rotation), the two main factors of which are the angular momentum of the parts before the formation of the planet and the angular momentum caused by the continuous accretion of gravity during the formation of the planet. These are not directly related to the distance from the Sun (the host star), so there is no direct causal logic to say that the closer a planet is to the Sun, the shorter the rotation period.

The slowest rotating planet in the solar system is Venus. Venus is the slowest planet in the solar system. Venus has a rotation period of 243 days, making it the slowest rotation of any major planet.

Venus rotates at the equator at only kilometre-hours, while the Earth rotates at the equator at about 1,600 kilometre-hours.

Venus is also the closest planet to Earth in the solar system and is surrounded by clouds and a thick atmosphere. Like Earth, Venus is also very young, about 500 million years old.

Kepler's three laws on the laws of planetary motion.

All the planets orbit the Sun in different elliptical orbits, and the Sun is at one of the focal points of these ellipses.

For each planet, the line between the planet and the Sun sweeps an equal area ("Area velocity"unchanged).

The ratio of the quadratic of the semi-major axis of the elliptical orbit of all the elliptical orbits of all the planets to the quadratic of the orbital period is equal.

a.Kepler's Three Laws were discovered on the basis of abandoning geocentrism and adopting heliocentrism, and on the basis of analyzing and studying the data recorded by his mentor, Tycho, on the continuous observation of planetary positions for more than 20 years.

b.Kepler's analysis and study of observation data has also gone through hardships and taken many detours. In the beginning, he used celestial motion"Divine","Perfect","Harmonious"The uniform circular motion model has a large error between the results obtained and the observed data.

Later, he doubted and abandoned the model of uniform circular motion, which sanctified the motion of celestial bodies, believed and respected the observations, and discovered that the orbits of the planets around the sun were not circles but ellipses, which led to the discovery of scientific laws.

c.The discovery of Kepler's three laws shows that successful scientific research must respect correct scientific observations and experimental data, establish scientific models that conform to the laws of facts, conduct painstaking analysis, calculation, and accept the test of practice in order to obtain truly correct conclusions.

Venus.

The rotation period of Venus is 243 Earth days, and the slow rotation of Venus is not due to its own reasons, but because it is too close to the sun and the aetheric wind that rotates on the inner side of Venus's orbit.

Introduction to Venus

Venus is the second planet from the sun outward among the eight planets in the solar system, with an orbital period of heaven and no natural moons. Venus was called Taibai, Xingxing or Dahuankong Town in ancient China, and its appearance in the east in the morning was called Qiming, and its appearance in the west at night was called Chang Gung.

During the period from Venus to the Western Han Dynasty, Sima Qian, the author of the "Historical Records of Tianguanshu", found that Taibai was white from actual observation, which was associated with the "Five Elements" doctrine and officially named it Venus. The English name is derived from Venus, the goddess of love and beauty in Roman mythology, and the ancient Greeks called Aphrodite, who is also the goddess of love and beauty in Greek mythology. The astronomical symbol of Venus is represented by the vanity mirror of Venus.

Venus is second only to the Moon in brightness in the night sky, and is the second largest and brightest celestial body, with an apparent magnitude of enough to illuminate a shadow on the ground. Since Venus is an inner planet on the inner side of the Earth, it never orbits far from the Sun: its maximum separation from the Sun is.

Venus is a terrestrial planet similar to Earth and is often referred to as Earth's sister star.

The General Assembly of the International Astronomical Union voted on the 24th to partially adopt a new definition of planets, which no longer considers Pluto, one of the traditional nine planets, as a planet because of its small diameter, and includes it as a "dwarf planet".After intense discussions, the General Assembly of the International Astronomical Union (IAU) announced the final version of the draft resolution on planetary definitions on the morning of the 24th. Astronomers will vote on the draft resolution on the afternoon of the 24th to determine the number of planets in the solar system.

The latest draft limits the definition of planets to the solar system. Due to the complexity of the definition and the delicate wording, the draft is divided into two parts, each of which requires a separate vote on the file. The first part states that "planets" are celestial bodies that orbit the Sun with a cavity that is gravitationally strong enough to overcome its rigid force to make a celestial body spherical, and capable of clearing other objects in the vicinity of its orbit.

These include Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, all of which were discovered before 1900. Objects that also have sufficient mass and are spherical in shape, but cannot clear other objects in the vicinity of their orbits are called "dwarf planets", and Pluto is a "dwarf planet".Other objects that orbit the Sun but do not meet the above conditions are collectively referred to as "small bodies of the solar system".

The second part of the draft provides for the addition of the word "classical" before the word "planetary" in the first part. According to the Executive Committee of the International Astronomical Union, these two parts of the resolution need to be voted on independently. And the number of planets in the solar system depends on whether the second part can pass through.

The latest issue of the official newspaper of the congress said that if the second part did not pass, then according to the provisions of the first part, the planets of the solar system would be limited to those eight planets discovered before 1900. The "dwarf planet" is not a planet, and Pluto will have no relationship with planetary status. If the second part passes, then the 8 planets discovered before 1900 will be called "classic planets", Pluto, Ceres, "Charon", which was originally thought to be a moon of Pluto, and an object tentatively numbered "2003UB313" will be called "dwarf planets".

"Dwarf planets" are also planets. According to the meeting arrangement, the conference will hold a closing meeting at 14 p.m. local time on the 24th (20 o'clock Beijing time on the 24th), when more than 2,500 astronomers from all over the world will vote on the draft resolution on the definition of planets. Mercury is about 4800 km in diameter, Venus is about 12104 km in diameter, Earth is about 13000 km in diameter, Mars is about 6762 km in diameter, Jupiter is about 143000 km in diameter, Saturn is about 119300 km in diameter, Uranus is about 51800 km in diameter, Neptune is about 49528 km in diameter, and Pluto is about 2400 km in diameter.

Yes! Generally slow.

Of course, note that slow here refers to revolution. The speed of rotation is another factor!

The reason is that the planets revolve around the Sun, and the centripetal force is provided by the Sun's gravitational pull on it. The gravitational force is inversely proportional to the square of the distance, which means that the farther away from the Sun, the greater the orbit of the half-width and the wider the diameter, the smaller the centripetal force, and the slower the revolution.

It is necessary to pay special attention here to the angular velocity, not necessarily the linear velocity!

If it is elliptical and circular, the aphelion of one planet is equal to the radius of the circular motion of another planet, then the elliptical circumference is slow.

Gravitation is the relationship between two stars, and the premise of comparing the gravitational force between the stars and the sun is that there is no great difference in the mass of the stars. If the orbits of the two planets are close and the mass difference between them is huge, there is still a difference in the orbital speed.

The slowest planet in the solar system with the slowest autobiography is Venus.

Venus's rotation period is 243 days, and around dawn, a particularly bright "morning star" is sometimes seen on the eastern horizon, which people call "morning star"; And at dusk, a very bright "twilight star" sometimes appears in the western afterglow, which people call "Chang Gung star". These two stars are actually one, Venus.

Venus is one of the nine planets in the solar system, and the second planet in descending order from closest to the sun. It is the closest planet to Earth, and Venus is called "Taibai" or "Taibai Star" in Chinese folklore. Venus travels at the equator at only 1,600 kilometres.

If you look at the solar system from the north pole of the Sun, all the planets rotate in a counterclockwise direction, but Venus rotates clockwise, and Venus rotates clockwise.

What planets are there in the solar system:

The solar system is the star system in which we live. It is a collection of the Sun's center and all the celestial bodies that are subject to the Sun's gravitational constraints: 8 planets (Pluto has been removed), at least 165 known moons, and hundreds of millions of small bodies in the solar system.

These small bodies include asteroids, Kuiper Belt objects, comets, and interstellar dust.

Broadly speaking, the domain of the solar system includes the Sun, 4 inner planets that resemble the Earth, an asteroid belt of many small rocks, 4 huge outer planets filled with gas, and a second small celestial region known as the Kuiper Belt. The orbits of the major celestial bodies in the solar system are in the vicinity of the plane of the Earth's orbit around the Sun (ecliptic). The planets are all very close to the ecliptic, and comets and Kuiper Belt objects usually have a more pronounced tilt.
