How close is Saturn to Earth?Saturn is the size of several Earths

A bunch of crap upstairs. Of all the planets in the solar system, Saturn is the fifth closest planet to Earth.

A few friends upstairs (except for the third floor), I don't know the answer, don't mislead people here, okay?I randomly excerpted a piece of text on the Internet and copied and pasted it directlyDon't look at what the subject is, Mars is like this, Jupiter is like this, is it okay to ask the moon and the sun how far away is to also excerpt such a text to make up the number?

In particular, I want to criticize the friends on the fourth floor, I have always affirmed your astronomical knowledge, and I have always thought that you are worthy of the title of netizen expert. But here I am very disappointed.

Okay, the landlord's question.

The average distance of Saturn from the Sun is astronomical units, and the eccentricity of the orbit. A roughly quantitative discussion, which we will ignore here.

The distance between the earth and the sun, 1 astronomical unit, eccentricity, and similarly, eccentricity is also ignored.

After making the above two approximations, it is not difficult to come up with a mathematical model.

The Sun is located in the center of the circle, the Earth and Saturn orbit around the Sun in a circular orbit, the radius of the Earth's revolution is 1 astronomical unit, and the radius of Saturn's motion around the Sun is an astronomical unit. So what is the distance between the two?

Obviously, the minimum is the astronomical unit (at this time it is Saturn opposition);

The farthest is the astronomical unit (this time is the Saturn conjunction).

So, under our approximate model, Saturn's distance varies periodically.

The landlord may ask, what exactly is the astronomical unit?The astronomical unit is the average distance between the Earth and the Sun, and the value is, approximately, 100 million kilometers. But I believe that in astronomy, no one would describe the distance from the Earth to Saturn in kilometers.

This problem is because it contains many moons of Jupiter. So, no one can count.

Saturn is equivalent to 830 Earths. With a diameter of 119,300 kilometers (twice that of Earth), it is the second largest planet in the solar system. The radius of the equator is 60,268 km, the mass of Saturn is twice that of the Earth, the volume is 830 times that of the Earth, the density is grams of cubic centimeters, and the mass is 95 times that of the Earth.

Earth is one of the eight planets in the solar system, and is the third planet in order of closest to the sun. It has a natural satellite, the Moon, and the two form a celestial system, the Earth-Moon System. Earth, as a planet, originated from the primordial solar nebula 4.6 billion years ago.

The Earth interacts with other celestial bodies in outer space, including the Sun and the Moon. The Earth is home to millions of living beings, including humans, and is the only celestial body in the universe where life is known. The radius of the Earth's equator is kilometers, the polar radius is kilometers, the average radius is about 6,371 kilometers, the equatorial circumference is about 40,076 kilometers, and 71% of the earth is oceans; 29% is land.

The reason why the Earth appears blue when seen from space is because the sky is another level of the Earth and is covered by seawater. The Earth is a large magnet, and through the north and south poles, the magnetic field can extend all the way to the Earth and beyond the altitude of more than 100,000 kilometers. The Earth is made up of the Earth's crust and mantle and its core, the temperature of which varies with depth, reaching 4,500 to 5,000 degrees Celsius at the center of the Earth at a depth of 6,371 km.

The Earth is not a complete sphere, it is an ellipsoid. The circumference of the Earth's equator is longer than the circumference of the prime meridian.

Saturn, one of the eight planets in the solar system, is located at the distance from the Sun (from near to far).

Sixth, the volume is second only to Jupiter. It is also a gas (wood-like) giant with Jupiter, Uranus and Neptune. In ancient China, it was also known as Zhenxing or Filling Star.

1] On February 16, 2016, the BBC** reported that in the solar system, Jupiter, Saturn, Uranus and Neptune all have rings, but completely different from the other three faint rings, Saturn's rings are very spectacular, which gives Saturn the nickname "Straw Hat Planet".

Saturn, known as the town star or fill-in star in ancient times, has a diameter of 119,300 kilometers, which is twice that of the earth.

Saturn is 830 Earth's size, and rightly so.

Among the nine planets in the solar system, Saturn is second only to Jupiter in size and mass, with a diameter of 119,300 kilometers. It is 745 times the volume of the Earth and twice the mass of the Earth.

Saturn (English saturn, Latin saturnus) is one of the eight planets in the solar system, the sixth closest to the Sun (from near to far), and second only to Jupiter in volume. It is also the same Jupiter-like planet as Jupiter, Uranus and Neptune. In ancient Europe (ancient Greece), Saturn was called Kronos, and in ancient China, it was also called Zhenxing or Filling.

Saturn is composed mainly of hydrogen, with small amounts of helium and trace elements, and its inner core consists of rock and ice, and its outer periphery is surrounded by several layers of metallic hydrogen and gas. The outermost layer of the atmosphere is usually bland in appearance, although sometimes long-lived features appear. When Saturn's winds reach 1,800 km/h, they are significantly faster than those on Jupiter.

Saturn's planetary magnetic field strength is between that of Earth and the stronger Jupiter.

It depends. Saturn and Earth have different orbital periods, and distances change from moment to moment. When the two are on the same side as the Sun, the distance is about 100 million kilometers.

When the two are on different sides of the Sun, the distance is relatively long, 100 million kilometers, while the average distance is 1.5 billion kilometers.

Physical properties: Due to its low density, high-speed rotation and fluid variability, Saturn is shaped as an ellipsoid, that is, the polar axis is relatively flat and the equator is relatively prominent, and the ratio of its equatorial diameter to the diameter of the poles differs by about 10% (120536 kilometers in the former and 108728 kilometers in the latter). The other gas planets, although also ellipsoids, are less prominent.

Although Saturn's core is much denser than water, Saturn is still the only planet in the solar system that is less dense than water due to its thicker atmosphere. Saturn is 95 times the mass of Earth, compared to 318 times the mass of Earth, but Jupiter's diameter is only about twice that of Saturn. Together, Jupiter and Saturn occupy 92% of the total planetary mass in the solar system.

Eight planets in the solar systemThe order from near to far from the Sun is:Mercury, Venus, Earth, Mars,Jupiter, Saturn, Uranus, Neptune. The two major planetary planets adjacent to Saturn are the Wood Tree Dead Star and the Uranus Slim Star.

Solar system.

Jupiter and Uranus, Saturn in the middle.

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

Venus is the second brightest celestial object in the night sky after the Moon, and its apparent magnitude can reach enough to cast 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. It has the thickest atmosphere of the four terrestrial planets, more than 96% of which is carbon dioxide, and the atmospheric pressure on the surface of Venus is 92 times that of Earth.

Mars is the closest planet to our EarthThe distance is about 55 million kilometers, and the maximum distance is more than 400 million kilometers. Close encounters between the two occur approximately once every 15 years. In 1988, the distance between Mars and Earth reached about 58.8 million kilometers, and in 2018 the distance between the two will reach 57.6 million kilometers.

But on August 27, 2003, Mars was only about 55.76 million kilometers away from Earth, the closest in 60,000 years.

Mars is the fourth closest planet to the Sun and the second smallest planet in the solar system after Mercury. Mars is called the "Luminous Star" in ancient Chinese books, and the "Mythical Mars Star" in ancient Western (ancient Rome) is the only guardian planet of the 12 zodiac signs Aries, not the guardian planet of Scorpio.

Martian topography.

Mars, like Earth, has a variety of terrains, including mountains, plains and canyons, and Mars is basically a desert planet, with sand dunes and gravel all over the surface. Due to factors such as less gravity, the terrain size is also different compared to the Earth.

The topography of the northern and southern hemispheres is striking: the north is a lowland filled with lava, and the south is an ancient highland full of craters, separated by a clear slope; The volcanic terrain is interspersed, there are numerous canyons, the North and South Poles are made up of dry ice (solid carbon dioxide) and water ice, and the rising wind-formed sand dunes are also widely spread across the planet.
