✨ Trivia
What it actually is
- 🛸 Its orbit family. An Amor-class object. It approaches Earth's orbit from outside without ever crossing it — named for the asteroid Amor, which swept past at 16 million km in 1932.
- 🌞 Closest approach. At its nearest it comes within 1.25 AU of the Sun — inside the orbit of Mars.
- 🔁 One lap. A single orbit around the Sun takes it about 4.4 years.
- 🥏 How far it roams. Its orbit swings between 1.25 and 4.12 AU from the Sun.
Sense of scale
- 🧱 Sense of scale. In everyday terms it is roughly 0.1× the height of Mount Everest.
Standing on it
- 🦘 Don't jump. Escape velocity here is only around 0.77 m/s. A determined jump would launch you off it and into your own orbit around the Sun.
By the numbers
- 📐 Size. Roughly 1.3 km across.
What's in a name
- 🔢 Designation. Known only by its catalogue designation — no name yet.

Why (331792) 2003 MT2 is a common neo
(331792) 2003 MT2 scores 19 points on Spacedle's rarity scale, which places it in the common tier. Another 3 points would lift it into a rarer tier.
That score comes from 4 science badges — Near-Earth object, Catalogue designation only, Amor: shadows Earth's orbit from outside and Brilliantly reflective surface — 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.
