When can I see Jupiter? What month?

Jupiter is the largest of the eight planets with the fastest autobiographical speed, so do you know in what season and in which month you can see Jupiter? Next, the constellation knowledge reveals the answer for everyone! Let's have a look!

In which month and season can Jupiter be seen? Jupiter's observation time is not based on seasons and months, but on the time before and after Jupiter's solar eclipse. When Jupiter eclipses, Jupiter is closest to the earth, with the brightest luminosity, which is most suitable for observation. In the months before and after Jupiter hit the sun, the brightness of Jupiter changed little. Jupiter hit the sun in the opposite direction. In this case, Jupiter is the brightest and can be seen all night. So the observation time is after dark. In the southeast in the first half of the night, in the southwest in the second half of the night, and in the south in the second half of the night. The earth goes around the sun once a year, and Jupiter goes around the sun once a year. Every 1 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 is "Jupiter rushing to the sun". At this time, Jupiter is closest to the earth, with the largest brightness and the largest visual circle from a telescope.

The composition of Jupiter is calculated by volume or gas molecular percentage. Jupiter's upper atmosphere is composed of about 88% ~ 92% hydrogen and about 8% ~ 12% helium. Because the mass of helium atom is four times that of hydrogen atom, when discussing the mass composition of Jupiter, the proportion will change: hydrogen and helium account for 75% and 24% of the total mass in the atmosphere respectively, and the rest 1% is other gaseous substances, including trace methane, water vapor, ammonia and silicon compounds. In addition, Jupiter also contains trace amounts of carbon, ethane, hydrogen sulfide, neon, oxygen, phosphine, sulfur and other substances. There are frozen ammonia crystals in the outermost layer of the atmosphere. Through infrared and ultraviolet measurements, trace amounts of benzene and hydrocarbons were also found on Jupiter. The ratio of hydrogen to helium in Jupiter's atmosphere is very close to the theoretical composition of the original solar nebula. However, the inert gas in Jupiter's atmosphere is two to three times that of the sun. Neon in the upper atmosphere accounts for only 20 millionths of the total mass, which is about one tenth of that of the sun. Helium is almost exhausted, but the proportion of helium in the sun is still 80%. This gap may be caused by the precipitation of elements into the planet. According to spectral analysis, Saturn is considered to be the most similar to Jupiter, but other gas planets, Uranus and Neptune, have lower ratios of hydrogen and helium. Because there is no analysis of the actual penetration of the spacecraft into the atmosphere, planets other than Jupiter still do not have accurate data on the number of heavy elements.
