What do you mean, "Mars rushes to the sun"?

The collision between Mars and the sun means that Mars and the sun are just on both sides of the earth, that is, the time difference between Mars and the sun is 180 degrees. Among the big planets, only exoplanets have such wonders. For example, Jupiter rushes to the sun and Saturn rushes to the sun. The meeting period between Mars and the Earth is 780 days, so we can only observe the Martian sun once every two years. In general, this is also a good time to observe Mars.

In June 65438 +65438 10+April 2020, Mars is about 63 million kilometers away from the earth. Although it is slightly farther than 58 million kilometers in 20 18, the observation conditions are good. After sunset, the orange-red Mars will slowly rise from the northeast, and then it will be visible almost all night, with a brightness of -2.6, brighter than Jupiter. This time, the apparent diameter of Mars reached 22.3 arc seconds, much larger than the next solar eclipse. Mars enthusiasts can use large-aperture high-magnification telescopes to observe the detailed features of the surface of Mars.

Generally speaking, when Mars blocks the sun, it is close to our earth, and its brightness is the brightest in a year. But at the same time, we also know that the orbit of Venus and the earth around the sun is not a perfect circle, but an elliptical orbit. In this way, Mars, like the Earth, has an apohelion and a perihelion. If mars moves to perihelion, it is called at this time? Dachong? On the contrary, Mars moves to the apohelion, which is called? Bug? . Dachong? This is the brightest time of Mars and the most suitable time for observation, and it can be seen all night.

It is precisely because the orbital time of the Earth and Mars is different that the collision time between Mars and the sun will change, with an average of 780 days, which means almost two years. But Mars has a long history, from 15 to 17 only once. The last time was on July 27th last year, and the next time will wait until the evening of September 15 19:38, 2035.

Many astronomers who like to observe Mars will not miss this opportunity, so this issue is coming!
