How long does it take for Eris to orbit the Sun?
WebOct 9, 2008 · Orbital periods are also given in units of the Earth's orbital period, which is a year. The eccentricity (e) is a number which measures how elliptical orbits are. If e = 0, the orbit is a circle. Most of the planets have eccentricities close to 0, so they must have orbits which are nearly circular. Last modified October 9, 2008 by Randy Russell. WebJul 27, 2024 · Well, one of the main reasons is that Mercury has a far shorter distance to travel than the planets that are farther out. This is also much less than Venus, which takes around 224 days to make it all the way round. Mercury is only 0.4 AU (astronomical units) away from the Sun, or approximately 36 million miles. WebIt takes 557 Earth years for Eris to make one orbit around the Sun. It has a highly eccentric orbit around the Sun, which causes its surface temperature to vary from -217 degrees Celsius to -243 degrees Celsius. Observations of Eris have led scientists to believe that it has frozen methane on its surface. At 2400 kilometers in diameter, Eris is ... howl hataitai
