The Earth has an eccentricity of 0.01671123. Where 0 is a perfect circle, and 1 is a parbola.
So by that it has a low eccentricity.

Which planets move in an elliptical orbit?
All the planets move with an elliptical orbit, but with a very low eccentricity.
What is the name of the sun being very far away?
The point in Earth's orbit where it's the furthest away from the Sun is called "aphelion".Because the Earth's orbit has low eccentricity, it's not that much further away than when it's nearest the Sun (perihelion); the difference between the two is only about 3%.
What orbit is still in the outermost part of earth's atmosphere?
A low Earth orbit is an orbit still in the outermost part of Earth's atmosphere. This kind of orbit occurs a few hundred kilometers into the atmosphere.
What type of orbit do the planets have to revolve around the sun?
According to Keplers first law of 1618 which has not been repealed yet, the planets each move in an elliptical orbit with the Sun occupying one focus. The shape of an ellipse is described by the eccentricity. For low eccentricity such as the planets' orbits have, the orbit is very close to being a circle but the most significant difference is that the Sun is off-centre.
How high above the earth does an orbit have to be?
Orbit can't be maintained in atmosphere. Some temporary low orbits are possible at lower heights. About the lowest possible orbit around the earth is 80 km high, but it will decay rapidly because it is still in the earth's atmosphere (the thermosphere). Even where the atmosphere is extremely thin (only a few molecules of gas in a cubic meter), the friction will eventually slow the orbit of a satellite or vehicle, and it will fall to earth.
What is the definition of low earth orbit?
An earth orbit that is lower to earth then both a medium and high earth orbit.
Does the space shuttle orbit the earth in what's called high orbit?
No. It is in low earth orbit.

All the planets move with an elliptical orbit, but with a very low eccentricity.
How would life be if the earths orbit was circular?
Earth's orbit is an ellipse, but not by very much. The eccentricity of earth's orbit (the measure that relates to the degree of ellipticity) is .016710219, which you can compare to the eccentricity of Pluto at .24880766. Pluto's orbit is very elliptical at roughtly .25. A perfect circle has a eccentricity of zero. Eccentricity of orbits can be anything from zero to less than one. If Earth's orbit were highly elliptical, it would probably interfere with orbits of other planets, Mars in particular. This would first of all call into question the definition of Earth and Mars as planets. It would also change the lengths of the seasons in some unpredicatable ways (some seasons would be much longer than others), which would have some serious effects on living things and stability of temperature.
What is the cause of high and low pressure areas?
the orbit of the moon around planet earth
What is the low pressure and high pressure area?
the orbit of the moon around planet earth
LEO satellites orbit the Earth with an altitude as low as miles?
A low Earth orbit (LEO) is an orbit around Earth as low as 100 miles and up to 1,240 miles close to the Earth's poles.
What is the name of the sun very far away?
The point in Earth's orbit where it's the furthest away from the Sun is called "aphelion".Because the Earth's orbit has low eccentricity, it's not that much further away than when it's nearest the Sun (perihelion); the difference between the two is only about 3%.

Does the shape of the earth affect the seasons?
While the Earth's orbit is an ellipse rather and a perfect circle, the eccentricity is fairly low, so not much of the seasonal weather changes are due to it. Most of the seasonal changes that we see each year are due to the fact that the Earth is tilted by 23.5 degrees from our orbit. So we have summer where the Earth is tilted toward the sun, and winter where the Earth is tilted away from it.
If a space vehicle is designed to orbit around the earth very slowly should it be put into a low or high orbit?
A high orbit. The effect of gravity gets less as you get further away from the Earth and so you'd need less speed to keep up.
