A Neptune-sized planet, TOI-3261 b, makes a scorchingly close orbit around its host star. Only the fourth object of its kind ever found, the planet could reveal clues as to how planets such as ...

Warm Neptune-size exoplanets are not nearly as common as super-Earths or hot Jupiters — and we are now closer to finding out why. Our galaxy apparently has a dearth of Neptune-size worlds that ...

All kinds of exoplanets orbit very close to their star. Some look like the Earth, others like Jupiter. Very few, however, are similar to Neptune. Why this anomaly in the distribution of exoplanets?

It is 60 times less dense than the densest "hot Neptune" discovered to date. However, the hot temperature and low density of the planet may have helped it survive the radiation emitted by its host ...

Astronomers from the European Space Agency (ESA) have discovered the shiniest known exoplanet in our universe to date. Named LTT9779 b, this ultra hot exoplanet revolves around its host star every ...

In the fire sign of Aries, that imagination takes on a hot-blooded hue. Neptune will move into Aries on March 30th where the planet will remain until October 22, 2025.

Illustration of LTT 9779 b, the only known ultra-hot Neptune. This planet orbits so close to its star that its atmosphere is scorching hot, glowing from its own heat while also reflecting ...

But only once have they found an "ultra-hot Neptune" — a Neptune-size world orbiting extremely close to its star. A year lasts under a day on this scorching planet, dubbed "LTT 9779 b." ...

A newly discovered distant mini-Neptune planet may possess its own atmosphere, ocean, or a combination of the two, even if they don't last for long. The extrasolar planet, or exoplanet, designated ...
