A new gas giant world discovered by citizen scientists using data from NASA's exoplanet-hunting spacecraft TESS is cool, ...

Meteorological analyst Jean Suriel reported that this Thursday, July 3, the Earth reached its farthest point from the Sun in ...

We have discovered two interstellar objects so far, ’Oumuamua and Comet 2I/Borisov. ’Oumuamua had no dust tail and a ...

Astronomers from the University of New Mexico, along with U.S. and international researchers, have confirmed the existence of ...

Sedna will reach its closest approach to the Sun in 2076, providing a remarkable space-faring opportunity that won’t come ...

For the dwarf planet candidate, one trip around the sun takes over 24,000 years. Its orbit challenges a proposed path for a hypothetical Planet Nine.

For planets with more exaggerated eccentricities, the changing distance can have a bigger impact. Sunlight on Mars, for example, can vary as much as 31 percent along its orbit.

Because Earth moves in an elliptical orbit around the sun, being further away means it travels slower along its orbit. This ...

O penAI's large language model (LLM) ChatGPT is surprisingly good at piloting spacecraft, according to a team that trained it ...

“In our study, we were not looking for a planet, only aiming to improve our understanding of the brown dwarfs.” Yet as they analysed the VLT’s data, the team noticed something strange about pair’s ...

Pluto, too, has a very elliptical orbit that pushes its variations to an extreme, Byrne said. These two factors — a planet's tilt and the shape of its orbit — can also change over time.

But at its furthest point during its orbit, 2017 OF201 is more than 1,600 astronomical units from the sun, while the closest point on its orbit is about 45 astronomical units.
