The Sun does not have a year, per se, as do the planets that revolve around it, but the Sun does revolve around the galactic core, along with all the other start in the Milky Way galaxy, with a period estimated to be around (2.25 to 2.50) x 108 Earth years.
The sun takes zero days to have a full year because the sun does not revolve.
True. The length of time that it takes to complete one orbit around the Sun is directly related to the distance of the orbit from the Sun.
The "Year" is based on the time taken to orbit the Sun. So the Sun can't have its own year.
The length of the Martian Year is 1.88 times the length of Earth's year.
Typically, this length of time is called a "year". Each planet's year is a different length than that of the other planets and increases as the planet is further from the Sun.
The length of time it takes to make a complete orbit around the sun.
The time taken by Callisto to orbit the Sun is essentially the same as the length of Jupiter's year: 11.86 earth years.
A revolution of the Earth around the Sun.
One year is the time it takes the earth to make one circle around the sun.
Once. that is how the length of our year determined.
the revolution of the sun around the earth.
As a general rule, the surface temp will go down and the length of the planet's "year" will increase the farther it is from the sun. There are exceptions, but that is the general rule.
