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 ...

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

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 ...

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 ...

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 ...

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 ...
