What is it called when planets revolve around the earth?
Please kindly note planets revolve round the sun only.
Why do planet revolve round the sun?
because sun is a star n planets revolve around the star not the other way round
Does the moon revolve round the planets?
Moons orbit planets Or rather moons and planets orbit their barycenter.
What makes the motion of planets revolutionary?
They revolve. They all have individual orbits round the Sun. The orbits closely approximate ellipses.
What did Copernicus do?
In the Dark Age of Science, it was believed that Earth was in the center of Solar System and all the planets including sun, revolve round the sun. This is called Geocentric Theory.Nicolas Copernicus, A Polish*Astronomer, proved that earth and other planets revolved round the sun. This is Heliocentric Theory.(Copernicus proposed the Heliocentric Theory in 1543, 64 years before the invention of telescope. I was all the work of his Mathematics.)_________________________________________________________________* Polish Astronomer is an Astronomer from Poland
What is meant by rotation of planets?
They go round and round. Not only do they turn on their polar axes, but they also revolve around the Sun. So the planets each have two types of revolution. The Earth turns on its axis every day, and it goes round the Sun once a year.
What is the theory that all planets revolve around earth?
That is part of an earlier theory of the planets' paths through the sky, devised by Ptolemy in AD 100. The planets were assumed to orbit round the Earth and for that reason the theory was described as geocentric. The Ptolemaic theory used combinations of circles to explain the planets' orbits. It explained the planets' movements quite accurately and was accepted for over 1000 years as correct because no major faults had been detected with it. In the 16th century the theory was re-examined by Copernicus who devised a new theory with the Sun at the centre (heliocentric), which in a sense was simpler, and the two theories coexisted as theories. In 1609 Johannes Kepler produced a new theory from the latest observations by Tycho Brahe using new equipment designed by himself with unprecedented accuracy. Kepler's theory had the Sun at the centre but used the novel idea of elliptical orbits, and this model was later confirmed by Newton's theoretical discoveries and also by subsequent accurate observations.
The word--------------- means to spin around like a top?
rotate - to revolve round a centre or axis
What is a sentence using the word revolve?
The ball was caught in the merry-go-round and began to revolve with it.
Did ptolemy believe in helio?
His theory was geo. The heliocentric theory is modern and has the Sun at the centre of the solar system with the planets going round it in nearly-circular orbits. Ptolemy's theory, a geocentric one, had the Earth at the centre, with everything else orbiting round it, but Ptolemy found an ingenious way of accounting for the planets' movements in the sky quite accurately. Ptolemy's method describes the planets' orbits in terms of a basic circular orbit, called the deferent but what goes round the deferent is a smaller circle, the epicycle, and the planet goes round the epicycle. It isn't difficult to see that this geometrical construction 'takes out' the Earth's movement round the Sun and explains the planets' movements as we see them from the Earth, while allowing the Earth to be fixed at the centre.
What does the sun revolve around the center of?
The Sun and its attendant planets in our Solar System, revolves round the center of the "Mikey Way" Galaxy. it takes about 200 million years to make one orbit.
Why does the earth revolve and the moon doesn't?
Moon also revolve. Earth revolve round the sun and moon revolve round the earth.
