On any planet, one year is defined by one orbit, or revolution, around its sun. One day is defined by the complete rotation spun around its own axis. The actual length of a year on a planet depends on how far it is from its sun, how much mass it has, and other variables. Since other planets' years, days, and time are different than ours, we measure them in Earth Years, Earth Days, or similar.
A year on any given planet is the time for that planet to revolve around the sun one time.
A planetary year is the amount of time it takes a planet to orbit the Sun. A planetary year on Earth is 365.26 days.
Any planet can appear in most months of any year, just not in the same months of every year.
The longest year on any planet that circles around our sun is on Pluto, which one year on Pluto roughly is 248 Earth years. <><><><><> Since Pluto is no longer considered to be a planet, the role of longest year falls to Neptune, with 168.4 years.
The time it takes for any given planet to make one complete revolution around its sun determines the length of its year.
A year. Any planet, any length of time, for that planet once around the sun is their year.
the rotation of the planet and its orbit
I have a science test this week and was wondering what causes air pressure differences on our planet?
The suns mass makes it rotate itself, and anything in its gravitational pull spins around the sun and spinning at the same time. That is how we have Day, Night and Year.
No, that's a `year`. A day is when the planet has spun once on its axis.
It would help to know which planet is considered to be in a mess.
Mercury, the closest planet to the sun, has an orbital period (year) equal to 88 Earth days.
