The newly discovered Atira asteroid offers a rare opportunity to study an object whose orbit lies completely inside Earth's orbit while crossing Venus's path.

Atira asteroids are difficult to observe because they spend most of their time between the Sun and Earth.

Observatories are racing to characterize Vatira asteroids that orbit closer to the Sun than Mercury.

The probe will pass through the Asteroid Belt to collect samples for analysis.

Several Trojan asteroids trail Jupiter along its orbit, hidden in the planet's Lagrange points.

The Trojan asteroid shared Jupiter's orbit while librating around the Sun–Jupiter L4 point, providing clues about the early solar system.

The probe's trajectory took it past several fragments in the Main Asteroid Belt, revealing unexpected mineral compositions.

Scientists discovered a rare metallic meteorite believed to have originated in the main asteroid belt.

A new documentary explored how asteroideans might adapt to the harsh conditions of the asteroid belt.

The spacecraft's radar detected an asteroidlike formation on the planet's surface.
