The heliocentric model is the one that has the Sun at the centre and the Earth the third planet out. We don't use the heliocentric model of Copernicus with its circles and epicycles, that was superseded by Kepler's model, but we still have the Sun at the centre.
In the most famous geocentric model devised by Ptolemy, the Sun goes round the Earth outside the orbits of the Moon, Mercury and Venus.
To enable Ptolemy's model to model the positions of Mercury and Venus correctly, they both follow circular orbits with large epicycles which 'take out' what we now understand is the Earth's circular orbit round the Sun.
Extra epicycles were added in Ptolemy's model to account for what we now understand as the eccentricity of the elliptical orbits and their slight inclination to the plane of the Earth's orbit.
Ptolemy's model was complicated but it only had to explain the observed positions of the planets, it did not have the additional modern requirement of giving a physical explanation of the planets' orbits. The modern theory uses Kepler's system of elliptical orbits with the Sun at the centre, backed up by Newton's detailed physical explanation of what is happening through the force of gravity and the laws of motion.
3rd planet from the Sun, roughly 98,000,000 miles.
The solar system with the Earth is in the Perseus arm of the Milky way Galaxy about 30 000 light years away from the center of the galaxy.
Earth is the 3rd planet from the first.
It is approx. 93,000,000 miles away from the Sun.
At the center - of everything.
Earth is the strongest planet in the solar system
Earth.
The Earth is the 3rd planet from the sun. (third rock from the sun, you remember that?)
Well, the basic position of Earth in our solar system is the third planet out from the Sun and it is in the group of the planets known as the 'inner planets' as they are closest to the Sun.
It is the 3rd planet from the sun.
Our moon orbits Earth, which is the third planet from the sun in our solar system.
Earth is a planet in the solar system
Earth is a planet, not a solar system.
Earth is the strongest planet in the solar system
The Earth is a planet in our solar system and the third planet from the sun. The Earth is the only planet within our solar system that can support life.
The largest planet in the solar system is Jupiter.
No, Earth is the fifth largest planet in our solar system.
No,Mars is. Earth is the fourth smallest planet known in the solar system.
Venus is the second planet from the Sun. After Mercury but before the Earth
It isn't. Earth ranks 5th in size. Jupiter is the largest planet in the solar system.
Up to now, Earth is the only planet in our solar system that can sustain life as we know it.
In the Solar System the answer is Earth since it is the only planet that has water.
