Due to gravitational forces by other planets in universe,earth changes its circular orbit into ellipse.it has enough tangential velocity to leave the orbit and go straight,but sun attracts it and vice versa.
An ellipsoid is a three dimensional figure whose plane sections are ellipses or circles. The Earth is an ellipsoid because it is a three dimensional shape, more specifically a sphere.

The maximum amount of an ellipse is called its major axis, and half of this distance is the semi major axiswhich is usually used to give the size of an ellipse. The semi major axis of Earths orbit, for example, is 150 million kilometers. It represents the average distance between the Earth and the sun and is called astronomical unit, or one AU
The Earth's orbit is close to being a circle. So, the ellipse is one with a small "eccentricity".
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.

Earth's orbit (revolution) around the Sun is not circular - it's an ellipse. However, this ellipse is fairly close to a circle.
The path of the Earth's orbit is an ellipse. The Sun is positioned at one of the two foci of the ellipse.
Earth's orbit is an ellipse; the Sun is at one of the ellipses focal points. (The other focal point has no astronomical significance.)
The orbit of the Earth around the Sun.It's an ellipse. Perhaps that's the answer. Or perhaps a revolution.It takes a year.It lies in the ecliptic.
All orbits are ellipses. You might describe an ellipse as a "flattened circle", but mathematically, a circle is a special version of an ellipse in which both foci are at the same spot.
If you mean the shape of the orbit, that's an ellipse.
