✨ 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 1.27 AU of the Sun — inside the orbit of Mars.
- 🔁 One lap. A single orbit around the Sun takes it about 1.8 years.
- 🥏 How far it roams. Its orbit swings between 1.27 and 1.7 AU from the Sun.
Sense of scale
- 🧱 Sense of scale. In everyday terms it is about 7.1 football pitches across.
Standing on it
- 🦘 Don't jump. Escape velocity here is only around 0.45 m/s. A determined jump would launch you off it and into your own orbit around the Sun.
By the numbers
- 📐 Estimated size. Nobody has measured its size directly. Assuming it reflects light like a typical asteroid, its brightness implies something roughly 746 metres across.
What's in a name
- 🔢 Designation. Known only by its catalogue designation — no name yet.

Why (419022) 2009 QF31 is a trash neo
(419022) 2009 QF31 scores 13 points on Spacedle's rarity scale, which places it in the trash tier. Another 2 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 Steeply tilted orbit (i > 40°) — 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.
