Strange discovery offers 'missing link' in planet formation: 'This fundamentally changes how we think about planetary systems'
A decade of observations of four planets around the young planetary system V1298 Tau revealed a rare, long-sought missing ...
The discovery of a strange wobbling planet has left astronomers confused but could reveal the secrets of planet formation. The new exoplanet, named TOI-1408 c, is situated about 455 light-years from ...
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 ...
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 ...
