Images from the Akatsuki spacecraft unveil what keeps Venus’s atmosphere rotating much faster than the planet itself. An international research team led by Takeshi Horinouchi of Hokkaido University ...

This morning, at the end of a 153-day and 400-million km cruise into the inner Solar System beginning with its launch on 9 November 2005, ESA’s Venus Express space probe fired its main engine at 09:17 ...

The European Space Agency’s (ESA) Venus Express spacecraft has discovered that our cloud-covered neighbor spins a little slower than previously measured. Peering through the dense atmosphere in the ...

Most importantly however, they found that collisions matching Venus's present-day rotation rate typically produce minimal debris disks that reside within Venus's synchronous orbit. This means the ...

The spacecraft suffered an engine anomaly that left it stuck in Earth's orbit for decades, and now it's slated for an uncontrolled reentry. Reading time: Reading time 2 minutes A 53-year-old Venus ...

A planet's year length depends on its distance from the Sun. Planets closer to the Sun have shorter years. A planet's rotation speed is unrelated to its year length. Planets' orbital speeds vary ...

You may have noticed in recent weeks that the planet Venus has slipped from the post-sunset sky, slimming into a crescent shape as it drops from view. Its reign as the bright "Evening Star" in 2023 is ...

Space can be a dangerous place, with massive rocks hurling through the solar system at fast speeds, some of which may be headed in our direction. NASA and other agencies keep a close watch on the ...

A hidden population of asteroids sharing Venus' orbit could threaten Earth in a few thousand years, and we might not even see them coming without better telescopes. These so-called Venus co-orbital ...

Simulations of asteroids near Venus reveal gaps in our ability to detect them. Astronomers are investigating a little-known and largely unseen group of asteroids that quietly orbit the sun alongside ...
