Trivia
Handle with care
- What 'hazardous' means. 'Potentially hazardous' is bookkeeping, not a prediction: it means the orbit passes within 0.05 AU of Earth's and the body is big enough to matter. Nothing on that list is known to be on a collision course.
- If it ever hit. A rock this size arriving at a typical 20 km/s would release around 8683 megatons — about 174 times the largest bomb ever detonated.
What it actually is
- Its orbit family. An Apollo-class object: its orbit is wider than Earth's but crosses it. Most known Earth-crossers belong to this family.
- Closest approach. At its nearest it comes within 1 AU of the Sun — inside the orbit of Mars.
- One lap. A single orbit around the Sun takes it about 1.3 years.
- How far it roams. Its orbit swings between 1 and 1.35 AU from the Sun.
Sense of scale
- Sense of scale. In everyday terms it is about 4.9 football pitches across.
Standing on it
- Don't jump. Escape velocity here is only around 0.31 m/s. A determined jump would launch you off it and into your own orbit around the Sun.

Why (778852) 2011 AM24 is a rare neo
(778852) 2011 AM24 scores 35 points on Spacedle's rarity scale, which places it in the rare tier. Another 15 points would lift it into a rarer tier.
That score comes from 6 science badges — Near-Earth object, Potentially hazardous, Tiny fragment (<1 km), Catalogue designation only, Apollo: crosses Earth's orbit and Darker than charcoal — each earned for a real, measurable property of the object. Rarity on Spacedle is never random: the more remarkable an object's astrophysics, the more badges it collects, the higher it scores, and the rarer it ranks.
