The eight planets in our solar system (yes, it's still weird for me to write "eight," too) orbit the sun in roughly circular paths, although they're ever-so-slightly ellipses instead of circles. A ...

Astronomers have spotted signs of an unusual, rainbow-like pattern decorating the surface of WASP-76b, a "hot Jupiter" exoplanet some 637 light-years away. The circular "glory" lights, if ...

Researchers based at Aarhus University measured the orbital eccentricity of 74 small extrasolar planets and found their orbits to be close to circular, similar to the planets in the solar system ...

Planets with a similar size to Earth have been found to follow a similar circular orbit, which could have implications in the search for life. Circular orbits can support a relatively stable climate.
