Observation time of Jupiter in 2020: 14 at 7: 58 on July 7th, 14 at 7: 58 on July 7th, Jupiter will perform "Rushing to the Sun". The sun is the best time to observe Jupiter, which is the closest and brightest to the earth. By then, if the weather is fine, the interested public can observe the great figures in this solar system almost all night, that is, a few days before and after the "Sun Rush".
Is Jupiter visible to the naked eye? Jupiter is the brightest star in the sky except Venus (only sometimes Mars is brighter than it). During Jupiter's eclipse, Jupiter was in Ophiuchus. For observers in the middle and high latitudes of the northern hemisphere, the horizon is very low and will not rise to a high enough position until midnight. With the help of a small telescope, amateurs can not only see the colorful stripes on Jupiter's surface and the "Great Red Spot" near its equator, but also see four Galileo satellites orbiting Jupiter. At that time, astronomers can also photograph its surface details, and their relative positions are different every day, just like a small "solar system". Jupiter can be seen with the naked eye, but nothing can be seen except Jupiter, the earth and the sun in a straight line. At this time, Jupiter is closest to the earth, with the brightest luminosity, which is most suitable for observation. If you look at it with the naked eye, there is no difference at all.
The direction of the observation guide is Jupiter -2.7 and so on. At midnight, the horizon is 37 degrees (based on geographical location 120E30N). When Jupiter Sagittarius rushes to the sun, it rises in the southeast after dusk and sets in the southwest before dawn, and it can be seen all night. During the solar eclipse, Jupiter runs in the sky of Gemini. Jupiter has risen after dark, so citizens only need to pay attention to the brightest star in the east, Jupiter, and its brightness will reach -2.7.
The eccentricity of Jupiter's orbit in time is close to zero. Whether Jupiter rushes to the sun at perihelion or at the original helion, the distance from Jupiter to the earth is similar. There is basically no big rush. In addition, when Jupiter blocks the sun, the yellow color of Jupiter differs from the sun by 180 degrees. Jupiter will rise as soon as the sun goes down.
