A decade of observations of four planets around the young planetary system V1298 Tau revealed a rare, long-sought missing ...

The star system V1298 Tau reveals that many planets begin as large, low-density worlds that slowly shrink and shed their ...

Planets orbit their parent stars while separated by enormous distances – in our solar system, planets are like grains of sand in a region the size of a football field. The time that planets take to ...

Simple axioms can seem too simple. That was the case for aerospace engineer Max Fagin, when he encountered the rule of thumb that orbit at the surface level of rocky planets takes two hours. Dubious, ...

Now, a new Nature study points to an answer by catching four planets at a stage most systems never show us: The awkward, ...

Astronomers from the University of Warwick have observed an exoplanet orbiting a star in just over 18 hours, the shortest orbital period ever observed for a planet of its type. It means that a single ...

A rare family of six exoplanets has been unlocked with the help of ESA’s Cheops mission. The planets in this family are all smaller than Neptune and revolve around their star HD110067 in a very ...

The orbital period is the time taken for a planet to make one complete circuit of the star. So, for example, two planets orbiting a star would be in a 2:1 resonance when one planet takes twice as long ...
