On the other hand, years depend on a planet''s revolutions around the Sun. This is a much easier, more intuitive concept – a sphere simply takes this and that much time to complete a circle (or, to be more specific, an ellipse) around our life-giving star. The farther a planet is from the Sun, the more time it will likely need to go around

Exoplanets
Overview Most of the exoplanets discovered so far are in a relatively small region of our galaxy, the Milky Way. ("Small" meaning within thousands of light-years of our solar system; one light-year equals 5.88 trillion miles, or 9.46 trillion kilometers.) Even the closest known exoplanet to Earth, Proxima Centauri b, is still about 4 light-years []
3.2: The Laws of Planetary Motion
For many years he worked to discover mathematical relationships governing planetary spacing and the time each planet took to go around the Sun. In 1619, Kepler discovered a basic relationship to relate the planets'' orbits to their relative distances from the Sun.
Planetary Age Calculator
Yes, most Planetary Age Calculators allow you to calculate your age on all major planets in the solar system, including Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Some may also include calculations for dwarf
Solar System data
The Sidereal Period is the time taken by the planet to return to the same place in its orbit, relative to the stars. Perihelion and Aphelion are the planet''s closest and furthest distances from the Sun, measured in Astronomical Units (AU). 1 AU is defined by the average distance from the Earth to the Sun. The globes of the planets

· The solar system''s several billion comets are found mainly in two distinct reservoirs. The more-distant one, called the Oort cloud, is a spherical shell surrounding the solar system at a distance of approximately 50,000 astronomical units (AU)—more than 1,000 times the distance of Pluto''s orbit. The other reservoir, the Kuiper belt, is a thick disk-shaped zone whose main

6 FAQs about [Years of planets]
How long is a year on other planets?
How long are years on other planets? A year is defined as the time it takes a planet to complete one revolution of the Sun, for Earth this is just over 365 days. This is also known as the orbital period. Unsurprisingly the the length of each planet’s year correlates with its distance from the Sun as seen in the graph above.
How long is a year on Earth?
A year on Earth is approximately 365 days. Why is that considered a year? Well, 365 days is about how long it takes for Earth to orbit all the way around the Sun one time. A year is measured by how long it takes a planet to orbit around its star. Earth orbits around the Sun in approximately 365 days. Credit: NASA/Terry Virts
How many dwarf planets are there?
In total, there are now five recognized dwarf planets. One year on Pluto is 248 Earth years, and its day lasts 153.3 Earth hours (just over 6 Earth days). This is how long a year is on other planets in our solar system, beginning with Mercury at about 176 Earth days to complete its orbit.
How many solar days does a year take?
In short, our planet takes 365.2564 solar days to complete a single orbit of the Sun, which is why we add an extra day to the calendar every four years (i.e. a Leap Year, which 2016 happens to be). But because our axis is tilted, there is considerable variation in the seasons during the course of a year.
What if you lived on a different planet?
If you had lived on a different planet your whole life, then you would be a different age due to the orbital differences. Listed below are the planets year lengths in earth days from shortest to longest. 1. Mercury: One year on planet Mercury takes just 87.97 earth days.
How long does it take to rotate a planet?
While earth takes 365 days to make one circuit, the closest planet, Mercury, takes only 88 days. Poor, ponderous, and distant Pluto takes a whopping 248 years for one revolution. Refer to the table with the rotation rates and revolution rates of all the planets. Why the huge differences in periods?
