Astronomers manning an asteroid warning system caught a glimpse of a large, bright object zipping through the solar system ...

Earth’s orbit around the Sun is not circular, but an ellipse that is slightly elongated with an eccentricity of 0.017. (An eccentricity of 0 is a circle, while the dwarf planet Pluto has a ...

Perihelion is the point at which an orbiting body is closest to the sun. The word comes from Greek and literally means around (peri) the sun (helios).

Our planet whirls around the sun in an ellipse, rather than a circle. ... How much the Earth’s orbit deviates from a perfect circle is measured by its eccentricity.

Venus’s eccentricity is 0.007. Earth’s is also low at 0.017, which is why our seasons are mostly about axial tilt, rather than distance from the Sun. Meanwhile, Mars has an e of 0.0934 .

Eccentricity. The Earth orbits the sun in an oval shape called an ellipse, with the sun at one of the two focal points (foci). Ellipticity is a measure of the shape of the oval and is defined by ...

An ellipse is a flattened circle, this “flatness” is defined as eccentricity and takes a value between 0 and 1. So a perfect circle can be thought of as an ellipse with an eccentricity of 0.
