Understanding Asteroids

The rocky and icy small bodies of the Solar System — where they live, what they are made of, how they group into families and populations, how spacecraft explore them, and how near-Earth objects are tracked. Built on real MPC/JPL data that reuses the platform's dwarf planets, asteroids, and missions; nothing is fabricated.

Beginner
  1. 1.1What is an asteroid?The leftover rocky and metallic building blocks of the Solar System.
  2. 1.2The main asteroid beltThe reservoir of most asteroids, between Mars and Jupiter.
  3. 1.3The largest asteroidsCeres, Vesta, Pallas, and the other giants of the belt.
  4. 1.4Dwarf planetsThe minor planets big enough to pull themselves round — Ceres, Pluto, Eris, and more.
Intermediate
  1. 2.1Near-Earth objectsThe Apollo, Aten, Amor, and Atira asteroids whose orbits approach ours.
  2. 2.2What asteroids are made ofCarbonaceous, silicaceous, and metallic taxonomy from their spectra.
  3. 2.3Asteroid familiesFragments of shattered parent bodies sharing similar orbits.
  4. 2.4Trojans and resonancesHow orbital resonances trap asteroids into distinctive populations.
Advanced
  1. 3.1Beyond NeptuneThe Kuiper Belt, scattered disc, and the distant detached objects.
  2. 3.2Exploring asteroidsThe spacecraft that have flown by, orbited, and landed on small bodies.
  3. 3.3Sample returnBringing pieces of Itokawa, Ryugu, and Bennu back to Earth.
  4. 3.4Planetary defenseFinding, tracking, and — if ever needed — deflecting hazardous asteroids.
