Rather, most TNOs have trajectories that keep them relatively close enough to Neptune for extended periods of time such that they can be controlled by the ice giant's gravity. The team ...

And we measure this in multiples of the strength of Earth's gravity, known as 1G. The first planet I'm travelling to is Neptune. Its gravity is just fractionally stronger than here on Earth.

Astronomers have discovered two exoplanets around TOI-1453, a star about 250 light years away. These two exoplanets, a super-Earth and a sub-Neptune, are common in the galaxy, yet are absent from our ...
