Astronomers have discovered two new exoplanets that are similar to other worlds found in the Milky Way, but unlike any in our ...

Young, close-orbiting exoplanets known as sub-Neptunes may form farther from their stars and migrate inward or lose their ...

The Sun is the largest object in the Solar System. The Sun’s huge gravitational field keeps many other objects – planets, dwarf planets, asteroids and comets – in orbit around it.

8 planets orbit the Sun. The closest are the four rocky planets, the remaining gas planets inhabit deeper space. The solar system is also home to many other cosmic bodies including asteroids ...

While most objects in our solar system orbit the same plane, and in the same direction, the orbit of these objects looks like this. Some of them orbit on a slight tilt. Others orbit backwards.

Other objects with bizarre orbits are 2008 KV42 and 2011 KT19 which move almost perpendicular to Neptune's orbit. “The best match for today’s outer solar system is a star slightly lighter than ...

The two exoplanets, or planets outside of our solar system, orbit a star called TOI-1453, which is slightly cooler and smaller than our sun. Located about 250 light-years from Earth in the Draco ...

A new classification scheme may help us better understand planet formation — including the history of our own family of worlds.

So exactly how many solar system moons have we found ... "The simplest definition [of a moon] would be an object that is in an orbit around a larger, non-stellar object," Ashton told Live Science.

In a review paper, astronomers trace the impact orbit of observed meteorite falls ... Its First Direct Images of Carbon Dioxide Outside Solar System Mar. 17, 2025 — The James Webb Space ...
