What's the date of Jupiter Day in 2020?
What is the date of Jupiter's eclipse in 2020: July 14 July14 Jupiter's eclipse: located in Sagittarius, with an apparent diameter of 47.6 "; About -2.6 and so on.
When Jupiter rushes to the sun, Jupiter is closest to the earth, with the brightest luminosity and the best observation effect. In the months before and after Jupiter hit the sun, the brightness of Jupiter changed little. When Jupiter hits the sun, Jupiter and the sun are in opposite positions. In this case, Jupiter is the brightest and most visible all night. So the observation time is after dark. In the southeast before midnight, in the southwest after midnight, and due south at midnight. The earth orbits the sun once a year, and Jupiter 1 1.84 years. Every year and 34 days, the earth and Jupiter reach a parallel position in orbit. At this time, the sun, the earth and Jupiter are in a straight line, which means "Jupiter rushes to the sun". At this time, Jupiter is closest to the earth and has the highest brightness. Seen from a telescope, the observation circle is the largest.
The period of Jupiter's revolution is much longer than that of the earth, but after the earth's solar impact on Jupiter, it can travel between Jupiter and the sun again in a little more than a circle, forming a solar impact on Jupiter again. So the period of Jupiter hitting the sun is 1 year and 34 days.
Features For exoplanets like Jupiter, because they revolve around the sun for a long period and are far away from the Earth, their moving speed on the star background is relatively slow. It will take five to six years for Jupiter to move near Taurus and Gemini, where the upper, middle and upper domes are relatively high. Jupiter is the largest planet in the solar system. Jupiter revolves around the sun on the outside of the earth, and there is an opportunity to rush to the sun every 400 1 day. Sunset rises in the east and can be seen all night. At this time, the observation time is the longest and the closest to the earth, which is a good time for observation. At this time, Jupiter's brightness is much better than usual, and it can be seen clearly with the naked eye. About 20 days before and after the sun hit, Jupiter rose from the eastern horizon in the evening, just after sunset, and did not set in the west until sunrise the next day, with a brightness of -2.6 magnitude. Therefore, astronomy enthusiasts can clearly see with the naked eye that this "oldest of the eight planets" shines in Ophiuchus all night. When the sun shines, celestial bodies can be seen all night, the brightness reaches the brightest, and the planet presents a complete circular surface. Harmony means that the eclipses of the two celestial bodies are the same, that is, from the earth, the two celestial bodies are in the same direction.
