Asteroid Dinkinesh, target No. 1 on Lucy's journey, turned out to be not one, but two (technically three) space rocks put together. Scientists finally gave its satellite a name.
Asteroids are space rocks thought to be the remains left over from the formation of the solar system. They range in size from tiny (the size of a car or so) to truly giant, with at least one - Ceres - gaining dwarf planet status. In our solar system, billions of asteroids are in the asteroid belt, a region around the sun between the orbits of Mars and Jupiter. Others stray from this region, and can potentially post an impact threat to the Earth. At least one interstellar asteroid, called 'Oumuamua, has passed through our solar system.

The Psyche spacecraft just fired a laser on its way to a metal asteroiod, in a test that could help speed up science transmissions across the solar system.
In the glare of the sun, an unknown number of near-Earth asteroids move on unseen orbits. A new generation of space telescopes could be our best defense against potential disaster.
The events of 2003 changed the direction of human space exploration — both in our timeline and that of the alternate history series "For All Mankind." The fourth season picks up in 2003.
Some companies hope to one day search for deposits that are literally out of this world — on asteroids.
Scientists have predicted for a long time that elements with around 164 protons could have a relatively long half-life, or even be stable.
Asteroid Dinkinesh is not only a binary, but its satellite is itself a "contact binary" consisting of two space rocks touching one another.
Japan's DESTINY+ mission to 3200 Phaethon, the parent body of the famous Geminid meteor shower, will have to wait a bit longer to get off the ground.
A sizable crowd turned out to see a small rock as the Smithsonian debuted the first display of a piece of the asteroid Bennu from the sample recently brought back by NASA's OSIRIS-REx mission.
NASA's Lucy spacecraft just flew by its first asteroid — and discovered that the space rock has a companion.
NASA's Lucy mission is set to visit several asteroids over 12 years, and the probe just successfully flew by target number one.
Rocks formed during the Chicxulub asteroid impact reveal fine dust particles were main drivers of the global winter which led to extinction of 75% of Earth's species.
On Wednesday, Nov. 1, NASA’s Lucy spacecraft will make its first flyby of an asteroid, zooming past a space rock named Dinkinesh before heading to the Trojan asteroids of Jupiter.
I use Moon and Mars rocks in my teaching and have a modest collection of meteorites. I marvel at the fact that I can hold in my hand something that is billions of years old from billions of miles away.
The public will get its first direct look at a fragment of the asteroid Bennu when the Smithsonian's National Museum of Natural History debuts its display of the NASA-returned sample on Nov. 3.
Scientists have confirmed that OSIRIS-REx brought home at least 70.3 grams of material from asteroid Bennu, surpassing its intended goal of 60 grams.
Naturally occurring superheavy elements beyond those listed in the periodic table could potentially explain why asteroid 33 Polyhymnia is so dense, new research suggests.
