Jakarta –
One year on Earth is equal to 365 days plus a few hours. One day on Earth is also equal to 366 days if it is a leap year like 2024, which is divisible by four. However, on other planets, one year can be equal to 225 days to 60,190 days.
The US National Aeronautics and Space Administration (NASA) on its Space Place page explains that the difference of one year on Earth compared to other planets is caused by the orbital path and gravitational force of the Sun. What’s that?
Influence of Orbital Path
The first reason the duration of each planet’s year varies is because of its distance around the Sun. This distance is called the orbital path.
The closer a planet is to the Sun, the shorter its orbital path. Every time you complete one orbital path, that is called one year.
Mercury, the planet closest to the Sun, has only 88 days in a year. Meanwhile, Neptune, the planet farthest from the Sun, has 60,190 days a year.
Influence of the Sun’s Gravitational Force
The second reason a year on each planet can have a different number of days is because of the gravitational force of the Sun. The closer a planet is to the Sun, the greater the Sun’s gravitational force pulling on the planet. The stronger the pull, the faster the planet orbits.
How Many Days Per Year on the Planet?
The length of the year on the planets of the Solar System is calculated from data from the NASA Solar System Dynamics website. Knowing the year on another planet and its calendar helps scientists schedule astronaut exploration there.
