The Solar System has just gotten a new official member. Currently, with the name of 2017 OF, this is a trans-Neptunian object (TNO). This means that it orbits the Sun further away than Neptune.

Astronomers measure the speed at which the solar system is hurtling through space by mapping surrounding galaxies and observing how light from other objects is shifted. New measurements, however, put ...

The planets in the solar system draw elliptical orbits around the sun. Regarding these orbits, astronomers have proposed the theory that 'sometimes they are stable and sometimes unstable,' and have ...

Forget what you learned in school. The solar system isn't just a flat disc of planets it's a 3D bubble moving through space.

Astronomers have uncovered a massive new trans-Neptunian object, 2017 OF201, lurking at the edge of our solar system. With an orbit stretching 25,000 years and a size that may qualify it as a dwarf ...

The Earth is our planet. It is one of eight planets that move around the sun, each in an oval shaped, elliptical orbit close elliptical orbitAn orbit that is the shape of an ellipse. An ellipse is ...

SPACE (KXAN) — A star flying through the night sky may be the fastest-moving solar system in our galaxy. Possibly a planet a little larger than Neptune orbiting a small star, the system could be ...

Learn how a possible ninth planet, the theoretical Planet X, could have acquired its wide orbit in the outer Solar System — a process that’s also applicable for other planets. Sam Walters is the ...

Saturn orbits the Sun at roughly 9.69 km/s, maintaining its grand system of rings as it cruises through space. Uranus moves at about 6.81 km/s, spinning on its unique sideways axis as it orbits the ...

The ARAQYS-D3 mission by Dcubed will demonstrate the ability to manufacture a solar array 15 meters long in orbit. Credit: Dcubed BREMEN, Germany — German satellite component company Dcubed is moving ...

In addition to planets such as Earth and Mars, there are many asteroids in the solar system. A map of such a solar system planet and 18,000 asteroids, along with their orbits, is available. An Orbit ...
