What time is taken by a planet to orbit the sun?
Different planets have different times to orbit the Sun. Mercury takes 88 days. Uranus takes 84 Earth years.
Do planets always move east against the stars?
All the planets do orbit the sun in the same direction. However, as we orbit the sun quicker than the planets further out from us, and slower than the ones inside us they do at times appear to be moving the other direction.
Why do different planets have different orbit times around the sun?
Because of factors like their mass and distance from the Sun
Why does the length of a day and year vary from planet to planet?
Some planets rotate faster or than others. Also the planets take different times to orbit the Sun.
Who realized planets orbit the sun?
Galileo used the telescope to support the heliocentric model (Planets orbit the sun)Nicolaus Copernicus worked out the arrangements of planets and how the move around the sun (heliocentric).Tycho Brahe and Johannes Kepler researched the planets' orbit and found that the orbit of each planet is an ellipse (Oval shape).
Why do moons take different times to orbit Jupiter?
Because, by Kepler's laws of motion, they have to go different speeds to maintain their orbits, and though they also have different distances to go because they are different distances from the planet, the speeds are so different that they take different amounts of time to orbit the planet.
Are the orbits of inner planets relatively closely spaced?
some times because we revolve in an elliptical orbit which is like the shape of an oval
Is Neptune retrograde?
No. All the planets in our solar system are prograde. At times it can appear retrograde when viewed from earth as an affect of our relative speed during certain times of our orbit.
Planet orbits sun?
Yes, in our solar system, the planets orbit the Sun (or more correctly, orbit a common center of gravity). In ancient times it was thought the planets and Sun orbited the Earth, but as with all good science, the notion was replaced as new and better evidence came to light.
Why is Sun in the middle of every planet?
The sun is a thousand times more massive than all the planets combined. The planets all orbit the sun for this reason--due strictly because of its great mass.
How many times does the Earth orbit the sun?
The sun NEVER orbits Earth. Earth orbits the sun. All of the other planets also orbit the sun.
Are circles orbits of the planets?
NO!!! The planets do NOT orbit in circles. They orbit the Sun in an ellipsoidal manner. An ellipse has two foci. The Sun lies at one of the foci, the other might be deemed to be a 'blind' focus. The Sun does NOT lie at the centre of the ellipse. Also the satellites(moons) orbit their parent planets in a similar manner. It has also been discovered that the planets in an an ellipsoidal manner. That is as each orbit is completed the planet 'over-shoot' their starting point, and the ellipse does not close . See Johannes Kepler, who gave us the Law of orbiting planets sweeping equal arcs in equal times , in 1602 AD.
