In 2020, a study confirmed that two planets orbited the nearby red dwarf, GJ 887. Now, astronomers have confirmed the ...

A team of scientists has confirmed that the nearby star GJ 887 hosts at least four planets, one of which could be a habitable ...

rotation. Here’s the puzzle: That is about 6 minutes, or one percent, longer than the radio rotational period measured by the Voyager 1 and Voyager 2 spacecraft, which flew by Saturn in 1980 and 1981.

Astronomers have found that the rotational profile of a nearby star, V889 Herculis, differs considerably from that of the Sun. The observation provides insights into the fundamental stellar ...

Planetary scientists have pinpointed the rotation period of Uranus — and it’s 28 seconds longer than they thought it was 1. Like other gas-giant planets, Uranus doesn’t have a rocky surface to look at ...
