Earth has an average eccentricity in its orbit of 0.0167.
This compares with 0.0068 for Venus and 0.205 for Mercury, which are the minimum and maximum eccentricities in the eight planets.
So, the Earth's orbit is not too far from circular.
In order of increasing eccentricity, the list of planets is:
Venus Neptune Earth Uranus Jupiter Saturn Mars Mercury.

How does the eccentricity of the earths orbit compare to the eccentricity of the other planets?
It is less than most of them: Venus .007, Neptune .009, Earth .017, Uranus .047, Jupiter .048, Saturn .056, Mars .093, Mercury .206.
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.
How does earth's size compare to other planet?
Earth is the biggest of the terrestrial or rocky planets, but smaller than any of the gas giants.
How does Earth compare in size to the other planets?
Earth is a little bigger than the other terrestrial planets (Mercury, Venus, and Mars), but the immensity of the jovian planets (Jupiter, Saturn, Uranus, and Neptune) cannot be matched by Earth's. Jupiter, the largest planet, has a diameter over eleven times greater than that of Earth.
How does your planet compare in size to the other planets?
small.

How does the Earth probably compare in orbital speed to the other planets?
The Earth moves faster than the planets that are farther from the Sun.
How can studying earth help scientists understand other planets?
Studying the earth helps scientists to understand other planets since the earth is part of the solar system. Scientists use the features of the earth to compare them with what other planets hold.
Does the size of a planet has any impact on the eccentricity of a planets orbit?
No but the sizes of OTHER planets and planetesimals can and do.
What do you compere Jupiter to?
You can compare it to many other planets including: Earth, Uranus, and Mars.
Which planet has an orbital eccentricity most like the orbital eccentricity of the earth?
The Earths orbit is fairly un-eccentric when compared to the other planets, with only Neptune and Venus having more regular (less eccentric) orbits. The eccentricity of earths orbit is 0.0167, the closest to this is Neptune's, with a value of 0.00859

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.
What is the actual shape of the Earths orbit around the Sun?
The actual shape of the earth's orbit around the sun is horrendously complicated. Partly because the earth does not orbit the sun and also because the orbit is influenced by the the gravitational attraction of the other planets. The earth does not orbit the sun: the centre of mass of the earth-sun system is at one of the foci of an ellipse whose eccentricity is 0.0167. The eccentricity varies from 0.0034 to 0.058.
