If you observe it often, you will find that one of the planets is always close to the moon and even blocked by the moon. The principle is the same as an eclipse. Then why is this?
Why are the planets in the solar system blocked by the moon? This is related to the included angle of planetary orbits. If the angle between the eight planets and the earth's revolution plane is less than 10 degrees based on the angle of the earth's revolution around the sun, it shows that they have the opportunity to line up with the earth.
Moreover, the plane of the moon's revolution around the earth has an included angle with the plane of the earth's rotation, which is only 5 degrees, almost the same. In other words, as long as the rotation time is long enough, there is always a chance to observe the phenomenon that the moon blocks other planets.
The easiest lunar eclipse to see is on April 28th, 2020. If you look at the sky carefully, you will find a very bright star next to the moon, which is the third brightest celestial body in the sky-Venus.
Of course, the first two are the sun and the moon. Some people will regret not seizing this observation opportunity, so when is the best time for the next observation? The answer is 65438+ 202 1 on February 7th next year, when the brightest eclipse of Venus will be observed. It is recommended to observe after sunset or before sunrise, which is the best.
Pictures of planets blocked by the moon taken by other telescopes are always blocked by the moon. Although we don't know when we can see them, or because the planets are not bright enough, we can still directly observe the pictures taken by others through telescopes. Let's look at some.
The picture above shows the process of the moon covering Mars.
The picture above shows the moon covering Saturn.
The picture above shows the moon covering Jupiter and its moons.
