Given the different Sun incidence in different positions in the orbit, it is necessary to define a standard point of the orbit of the planet, to define the planet position in the orbit at each moment of the year w.r.t such point; this point is called with several names: vernal equinox, spring equinox, March equinox, all equivalent, and named considering northern hemisphere seasons.
It applies to the elapsed time where planets return to the same kind of phenomenon or location, such as when any planet returns between its consecutive observed conjunctions with or oppositions to the Sun. For example, Jupiter has a synodic period of 398.8 days from Earth; thus, Jupiter's opposition occurs once roughly every 13 months.
Jupiter radiates more heat than it receives through solar radiation, due to the Kelvin–Helmholtz mechanism within its contracting interior. [70]: 30 [71] This process causes Jupiter to shrink by about 1 mm (0.039 in) per year. [72] [73] At the time of its formation, Jupiter was hotter and was about twice its current diameter. [74]
It's Jupiter season. You can observe the massive planet yourself every night. Let's talk about that.
A synodic day (or synodic rotation period or solar day) is the period for a celestial object to rotate once in relation to the star it is orbiting, and is the basis of solar time. The synodic day is distinguished from the sidereal day, which is one complete rotation in relation to distant stars [1] and is the basis of sidereal time.
The best nights of all of 2022 to see Jupiter in the night sky are about to take place as the planet takes center stage in the night sky, a showing unlike any other in nearly six decades. The sun ...
