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

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

Thanks to the discovery of thousands of exoplanets to date, we know that planets bigger than Earth but smaller than Neptune ...

Astronomers have identified a vast, cotton-candy–light “super‑puff” world that loops around its star in a wildly misaligned ...

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 ...

Scientists have detected and validated two of the longest-period exoplanets found by TESS to date. These long period large exoplanets orbit a K dwarf star and belong to a class of planets known as ...

AAPS, and three low-mass (ie Saturnian- or sub-Saturnian-mass planets). The multiple planet systems include two planets detected around the star mu Ara (in the constellation of Ara "The Altar"). The ...

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 ...

A comet's orbital period is fundamentally independent of its own mass, relying instead on orbital dimensions and the central star's mass. However, outgassing—the escape of gas and dust from a ...

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 ...
