The planet's orbit also plays a crucial role. A highly elliptical orbit, like that of Kepler-735c, can lead to extreme climatic variations. The presence of liquid water is another essential criterion.

A mysterious visitor from another solar system could be an alien spacecraft, according to a leading Harvard astronomer.

The discovery of the exoplanet, a super-Earth called Kepler-735c, is all down to something called transit timing variations, ...

Astronomers have uncovered a distant celestial body that may be a new dwarf planet, orbiting the Sun from more than twice the distance of Pluto. Found by researchers at the Institute for Advanced ...

It is highly elliptical, with an eccentricity of 0.44. For comparison, Earth 's orbit has an eccentricity of 0.0167 and is therefore close to circular; at the other extreme, an orbital ...

Discovered in 1930 after a nearly year-long telescopic search by a young observatory assistant named Clyde Tombaugh, Pluto is so faint and so distant—its 248-year orbit averages 3.7 billion ...

Before looking for Mercury, there is a simple rule. Never point binoculars or telescopes towards the Sun. It is best to wait for the Sun to have set. This will give you more than an hour to spot ...
