Astronomers Have Discovered a 2-km Asteroid Orbiting Closer to the Sun than Venus

Astronomers have painstakingly built models of the asteroid population, and those models predict that there will be ~1 km sized asteroids that orbit closer to the Sun than Venus does. The problem is, nobody’s been able to find one. Until now.

Astronomers working with the Zwicky Transient Facility say they’ve finally found one.

New small satellite mission to rendezvous with binary asteroids

The University of Colorado Boulder and Lockheed Martin will soon lead a new space mission to capture the first-ever closeup look at a mysterious class of solar system objects: binary asteroids.

These bodies are pairs of asteroids that orbit around each other in space, much like the Earth and Moon.

How small particles could reshape Bennu and other asteroids

In January 2019, NASA’s OSIRIS-REx spacecraft was orbiting asteroid Bennu when the spacecraft’s cameras caught something unexpected: Thousands of tiny bits of material, some just the size of marbles, began to bounce off the surface of the asteroid – like a game of ping-pong in space. Since then, many such particle ejection events have been observed at Bennu’s surface.

Completely harmless asteroid almost certainly won’t hit Earth just before the US election

In a year of devastating wildfires, destructive derechos, early and active hurricanes, widespread social unrest, contentious politics and more — all amid an unprecedented global pandemic — it might seem fitting that ‘asteroid impact’ would be added to the 2020 bingo card.

While weekend headlines buzzed over the prediction of an asteroid hitting Earth on November 2,

The Sun May Have Started Its Life with a Binary Companion

A new theory published in The Astrophysical Journal Letters by scientists from Harvard University suggests that the Sun may once have had a binary companion of similar mass. If confirmed, the presence of an early stellar companion increases the likelihood that the Oort cloud was formed as observed and that Planet Nine was captured rather than formed within the solar system.

Tiny Asteroid Buzzes by Earth – the Closest Flyby on Record (Almost)

An SUV-size space rock flew past our planet over the weekend and was detected by a NASA-funded asteroid survey as it departed. Near Earth Asteroids, or NEAs, pass by our home planet all the time. But an SUV-size asteroid set the record this past weekend for coming closer to Earth than any other known NEA: It passed 1,830 miles (2,950 kilometers) above the southern Indian Ocean on Sunday,

Dwarf planet Ceres is an ocean world: study suggests.

The dwarf planet Ceres — long believed to be a barren space rock — is an ocean world with reservoirs of sea water beneath its surface, the results of a major exploration mission showed Monday.

Ceres is the largest object in the asteroid belt between Mars and Jupiter and has its own gravity,

There Might Be an Entire Orbit, Filled with Asteroids that Came from Outside the Solar System

Aliens could be all around us. Lurking on the edge, waiting to invade our solar system. Not little green creatures, but asteroids from other stars. That’s the conclusion of a new study published in the Monthly Notices of the Royal Astronomical Society.

The outer solar system is filled with asteroids and comets.
