Why do you think planets do not have same orbits?
It's because each planets is a collection of all the debris that was going round in a similar orbit before the planets were formed. So the planets only survived to the present day by having different orbits.
What astronomer discovered that the orbits of the planets are elliptical rather than round?
Johannes Kepler.
Is Copernicus theory correct?
No physical theory is completely correct, because measurements always have a built-in error that you hope is small. But Copernicus's theory explaining in detail how the planets move was accurate enough for its time and was only found lacking later when observational techniques became sufficiently refined to show its errors. In modern times we have better theories for planetary orbits but Copernicus's general idea that all the planets orbit round the Sun is now generally accepted since Newton's theoretical discoveries, which were applied to showed that the Sun is far more massive than anything else in the solar system.
What do planets do when they orbit the earth?
There are no planets orbiting the Earth because all eight of them orbit the Sun. But the Moon orbits the Earth, and all it does is go round and round in a rather complicated orbit which is disturbed by the Sun's gravity.
How did galileo and newtons insights into physics help to make Copernicus' model more plausible?
In the end it was Kepler's model that was accepted as true. Copernicus's model with its circles and epicycles was replaced by Kepler's model with elliptical orbits that were eventually explained by the theory of gravity. The only part of Copernicus's model that has lasted is the idea that the Earth is in orbit round the Sun, which is accepted because Newton's discoveries showed that the Sun is far more massive than all the planets combined.
Orbits of planets are not round but are?
ither elliptical, heliocentric, or position!!!
Who drew a model that showed the sun and planets going round the earth?
Copernicus
Do the inner planets have direct or in direct orbit?
All the planets have direct orbits round the Sun.
How does the orbits effect the way planets move?
Orbits help a planet move because of gravitational pull which makes the planet orbit round and round. The planets orbit around the son and the moon orbits around earth. Hope this helps!
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
Is Mars round?
The planet Mars is round in shape. All of the planets in our solar system are orbits. The gravitational pull of the sun has formed the planets to be around.
What makes the motion of planets revolutionary?
They revolve. They all have individual orbits round the Sun. The orbits closely approximate ellipses.
What are the orbits of the gas giant planets?
They are the path taken by the gas giant planets (that is Jupiter and Saturn) as they go round the Sun.

Who proposed a heliometric model of the universe in which the planets revolve at diffrent points in their orbits?
If you mean a heliocentric model (Sun at the centre) with the planets moving in epicycles base on circular orbits, it was Copernicus. The model had a point called the deferent moving round a circle, and then an epicycle (small circle) centred on the deferent, with the planet moving round the epicycle.The planet, for example the Earth, moves round the epicycle once a year, while the deferent moves round the main circle once a year. That simple model, with one epicycle, represents a circle with the centre offset, which is a good model of the Earth's orbit. Other epicycles were added to take care of orbital inclination, and so on. Copernicus's model of the solar system had 48 epicycles althogether.
