Venus is an inner planet, and if you look at it from Earth with a telescope, you will see that it has a phase change.
The orbit of Venus is larger than that of Mercury.
of the big. When proceeding at the maximum elongation angle in the west (to the right of the Sun) or east (to the left of the Sun), it appears to be twice as far from the Sun as Mercury from the Sun. Venus is one of the brightest objects in the sky, and the best time to observe it is probably when the Sun is right on the horizon.
The following times. It is important to note that you should never look directly at the sun with your eyes. The sun sets and Venus then sets, which is now to the left of the Sun; Venus rises first before the Sun rises, and it is on the right side of the Sun.
It is easy to distinguish Venus, which is bright and slightly yellowish. When Venus is in the shape of a large "crescent", it is most appropriate to observe it with binoculars. At this time, Venus is located between the maximum elongation point and the subconjunction, and when Venus is between the Earth and the Sun, it will not be visible, so pay attention to adjust the focal length of the telescope so that it can observe distant objects.
Venus is located in the middle to the right, brighter than all the other planets or stars, Jupiter.
Located in the middle of the top. Thank you.

Venus appears in the eastern sky before dawn and is known as the morning star, and after dusk in the western sky, it is known as Chang Gung. 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.

Different times and different locations.
Since Venus is located on the inner side of the Earth's orbit, Venus is always moving near the Sun and moving with the Sun when viewed from Earth. If we take the Earth as the apex, connecting Venus and the Sun will form an angle. We found that the angle of this angle is small, and the maximum angle does not exceed 47°.
Therefore, Venus always appears near the Sun and does not exceed a narrow angle range of 47° at its maximum.
Venus does not reach its maximum brightness until just before sunrise or after sunset. It sometimes appears in the eastern sky before dawn and is called "enlightenment"; Sometimes it appears in the western sky after dusk and is called "Chang Gung".

The position of Venus is in the eastern sky before dawn, it is called Qiming, if it is after dusk, it will appear in the western sky, it is called Chang Geng, Venus is one of the eight planets in the solar system, the second planet from the sun to the outside, because the orbital rotation period is 224.7 days, there is no natural satellite, Venus is second only to the earth in the brightness of the night sky, it belongs to the second brightest celestial body, but because Venus belongs to the inner planet of the earth, Therefore, it will never move away from the sun, and the maximum distance of Venus from the sun is 47.8 degrees, and it is an earth-like planet that is more similar to the earth.

Venus is in the west near the horizon at night. Venus is one of the eight planets in the solar system. In order of distance from the Sun, it is the second, the astronomical unit of distance from the Sun. The orbital period is Earth Day.
Venus, which is the closest planet to Earth (sometimes Mars is closer). It appears in the eastern sky early in the morning called "enlightenment"; In the evening, it is called "Chang Gung" and is located on the west side of the sky. It reaches its brightest point just before sunrise or after sunset, and its brightness is second only to the moon in the night sky.

It is impossible to find Venus in the night sky late at nightWhether it is spring, summer, autumn or winter, or scorching heat and cold, Venus can only be found at dawn or evening not very far from the sun. This is due to the fact that Venus's orbit around the Sun is on the inner side of the Earth's orbit. In the dead of night, we are facing away from the Sun, and of course we can't see Venus, which is illuminated by the Sun on the inner side of the Earth's orbit.
It is also impossible for humans to observe Mercury in the middle of the night. Mercury is the most difficult of the five planets visible to the naked eye, and because it is closer to the Sun, people on Earth can only catch a glimpse of it before sunrise or less than 1 hour after sunset, and at very close to the horizon.
Five planets, sometimes people with very good eyesight are able to observe Uranus with the naked eye. Uranus's apparent magnitude is generally between solstice, and the ultimate apparent magnitude visible to the naked eye is around the corner.
Historically, Uranus was observed before the invention of the telescope, but because it was far from the Earth and its position did not change significantly, it was regarded as a star for a long time. Later, Laplace determined that it was a planet revolving around the Sun based on the calculations of gravitational force.
Neptune can only be observed with the help of an astronomical telescope, and Ceres, a dwarf planet that is closer to Earth than Jupiter, is too small to be observed by the naked eye.
Venus is called Venus because in the early days of scientific development, human beings had limited knowledge and did not know how to distinguish the planets, so they named them according to the five elements of yin and yang, which are visible from them. >>>More
Summary. Moon sign.
The sun affects the surface and the inside of the human personality, just as under the sun's rays, in addition to the entity we see, there is also a shadow; And the sun sign is an entity that others can see, and the ascendant sign is that shadow. But this entity was formed because of the moon sign. >>>More

The heart of the mouth fossa "in the sternum."
Directly below , at the junction of the two costal arches, in the upper abdomen, there is a depression just above the umbilicus. There are generally two types of uncomfortable heart and mouth fossa, one is heart disease and the other is gastrointestinal disease. Examples include acute and chronic gastroenteritis, gastroduodenal ulcer, gastric reflux. >>>More
