yes because because if the earth is spinning it has to be spinning as well.

What was the greatest inaccuracy in Copernicus model of the solar system?
Copernicus mistakenly thought that our earth was the center of our universe, with the sun and other planets orbiting earth.
Who discovered true shape of the planetary orbits?
Johannes Kepler showed that IF the planetary orbits are elliptical,THEN that would explain the measurements that Tycho Brahe collectedduring his whole life.Isaac Newton showed that IF gravity works the way he thought it does,THEN the planetary orbits would have to be elliptical.Both of these are only theories. They have never been proven.
Kepler's first law worked where Copernicus' original heliocentric model failed because Kepler described the orbits as?
Copernicus's theory did not fail but it was not as accurate as the Kepler model because it did not include elliptical orbits for the planets, as Kepler's model did. However the data for calculating the elliptical orbits did not become available until well after Copernicus's death so he had no chance of knowing about this change. Copernicus's model which used circles and epicycles was accurate to the standard of the observations that were available to him.
What is a halley's comet orbit like?
All orbits are ellipses. Some orbits, like the orbit of the Earth around the Sun, are almost (but not quite) circular. Other objects, like the Moon or Mars, have orbits that are more distinctly oval shaped.Comets have elliptical orbits with very high eccentricity; they are stretched so that they come quite close to the Sun, but still go dozens or hundreds of AU away. Some comets are less severely eccentric. Halley's Comet, for example, only goes out to about 30AU with a period of 76 years, while Comet Hale-Bopp has a period of closer to 2200 years.
What is The purpose of describing planetary orbits in terms of epicycles and deferents?
The purpose of describing planetary orbits in terms of epicycles and deferents was to explain the apparent motion of the planets. In the geocentric model of the universe, the Earth was at the center, and the planets orbited around it. However, the planets did not move in perfect circles. They would sometimes appear to slow down or even reverse direction. This was called retrograde motion. The epicycle and deferent model was an attempt to explain retrograde motion. In this model, the planet was thought to move in a small circle called an epicycle, which in turn moved around a larger circle called a deferent. The center of the epicycle was not at the center of the deferent, but was offset from it. This offset caused the planet to appear to slow down or even reverse direction as it moved around the deferent.
What is the dingbat answer for noonmidnight?

If the planets' orbits were circular would their distance from the sun always be the same?
Yes. However, the orbits of all planets are elliptical. Some planets, like Earth, have a very low "eccentricity", which is a measure of how non-circular they are. Earth's orbit is not quite circular, but fairly close. Other planets, like Mars, have more eccentric orbits, and their perihelion and aphelion distances are substantially different.
Among elliptical orbits are some more circular than others?
Yes some elliptical orbits are more circular than others
What is the shape of our solar system orbits?
circular
Why should the orbit be circular?
Orbits sould be circular because the centripetal force that keeps objects in circular motion is constant (it is gravity!)
What 2 planets have the most circular orbits?
venus and pluto
What 2 planets have most circular orbits?
venus and pluto
Why was Kepler not satisfied with the circle he calculated to fit most of the observed locations of mars?
The orbits of the planets, including Mars, are eliptical, not circular. Keplers observed positions did not fit a circular orbit. The differences led him to discover that the orbits were not circular, but eliptical.
Even though orbits are ellipes what shape is a typical planet's orbits most like?
Planetry orbits are elliptical. Most planet's orbits are nearly circular apart from Mercury and Pluto.
Why your planets revolve in elliptical orbit rather than circular orbit?
Circular orbits are unstable; any outside influence (i.e. other planets) will distort them. Elliptical orbits are self adjusting.
Who thought that the earth was the centre of the universe and that the planets had circular orbits?
Ptolemy, but he was wrong the sun is in the center and planets have elliptical orbits.
What two planets has the most circular orbits?
Pluto and Abby University
