A three-legged robot named SpaceHopper could help combat challenges of exploring low-gravity environments, such as asteroids or moons.

A newly discovered space rock will harmlessly pass by Earth today. Still, at less than a tenth the distance to the moon, asteroid 2024 GJ2 will miss the planet by the skin of its teeth.

Near-Earth asteroid Apophis will not collide with another space rock until its close approach to Earth in 2029, a new analysis finds.
