Database of asteroids, moons and planetary bodies with physical data, orbits and rendezvous delta-v from NASA/JPL
Largest M-type asteroid, potentially an exposed planetary core. One of the most massive objects in the asteroid belt. Target of NASA Psyche mission.
Near-Earth asteroid about 2.3 km across. Radar echoes indicate a metallic (nickel-iron) composition (Ostro et al., Science, 1991).
Highly accessible NEA with a low rendezvous delta-v (about 4.9 km/s from low Earth orbit).
One of the lowest delta-v NEAs known. May be spent rocket stage or asteroid.
Was the baseline target for NASA's proposed Asteroid Redirect Mission. C-type, likely water-bearing.
Small near-Earth asteroid.
Elongated near-Earth asteroid, about 500 m long and 150 m wide according to NASA Goldstone radar observations in 2023.
Small NEA that passed close to Earth in July 2015.
Large C-type asteroid, likely water-rich.
Aten-group near-Earth asteroid about 3.3 km across. Named after the Egyptian deity Amun.
S-type asteroid visited by Stardust mission en route to comet Wild 2.
Will pass extremely close to Earth in 2029. Target of ESA RAMSES mission. Named after Egyptian god of chaos.
Fourth largest moon of Uranus. Brightest of Uranian moons with youngest surface.
Potentially hazardous asteroid visited by OSIRIS-REx. Samples returned in 2023. Rich in water and organics.
Most heavily cratered body in solar system. Possible subsurface ocean. Outside Jupiter radiation belts.
Largest object in asteroid belt. Contains significant water ice and may have subsurface ocean. Dawn mission revealed bright spots and cryovolcanism.
Pluto's largest moon, nearly half Pluto's size. Binary dwarf planet system.
Large C-type main belt asteroid.
Smaller moon of Mars. Very low surface gravity. Potential staging base for Mars missions.
Binary asteroid system. Target of NASA DART planetary defense mission that successfully altered orbit of moon Dimorphos.
Active water geysers from subsurface ocean. Potential habitable environment.
First asteroid orbited by a spacecraft (NEAR Shoemaker). S-type with significant metal content. Peanut shape.
Ice-covered moon with subsurface ocean. Potential for life. Target of Europa Clipper mission.
Largest moon in solar system. Has magnetic field and subsurface ocean. Target of ESA JUICE mission.
First asteroid visited by spacecraft (Galileo). S-type main belt asteroid.
Fourth largest asteroid. Nearly spherical, may qualify as dwarf planet.
S-type asteroid with moon Dactyl (first asteroid moon discovered).
Fifth largest asteroid by volume. B-type with water content.
Most volcanically active body in solar system. Extreme radiation environment.
First asteroid from which samples were returned (Hayabusa). Rubble pile with contact binary structure.
M-type asteroid visited by Rosetta. Unusual for its spectral class.
Fourth planet. Primary target for human colonization. Water ice at poles and subsurface. Rich in iron oxide.
Very dark C-type asteroid with extremely slow rotation. Heavily cratered.
Closest planet to Sun. Large iron core (70% of mass). Extreme temperature variations. Water ice in shadowed craters.
Small icy moon with giant Herschel crater ("Death Star" appearance). May have internal ocean.
Smallest and innermost of Uranus major moons. Extreme surface features suggest violent geological history.
Earth's only natural satellite. Primary target for human settlement. Water ice at poles, helium-3 in regolith.
Highly accessible X-type NEA. Was candidate for early asteroid missions.
Third largest asteroid. Highly inclined orbit makes access challenging.
Parent body of Geminid meteor shower. Target of JAXA DESTINY+ mission. Unusual blue B-type.
Larger moon of Mars. May be captured asteroid or formed from Mars debris. Target of JAXA MMX sample return.
Largest known dwarf planet. Heart-shaped nitrogen ice plain. Complex atmosphere and active geology.
Aten-class NEA with C-type spectrum indicating water content.
Second largest moon of Saturn. Mostly water ice.
Rubble-pile asteroid visited by Hayabusa2. Samples returned to Earth in 2020 revealed abundant water and organic compounds.
Triple asteroid system with two moons (Romulus and Remus).
Saturn's largest moon with thick atmosphere. Lakes of liquid methane/ethane. Target of NASA Dragonfly mission.
Small near-Earth asteroid flown past by Hayabusa2 in July 2026.
Largest moon of Neptune. Retrograde orbit suggests captured KBO. Active geysers.
Earth's twin in size. Extreme surface conditions (460C, 90 atm). Sulfuric acid clouds. Target of upcoming VERITAS and DAVINCI missions.
Second largest asteroid. Differentiated body with iron core. Source of HED meteorites. Studied by Dawn mission.
