Trivia
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 3 years.
- How far it roams. Its orbit swings between 1 and 3.17 AU from the Sun.
Sense of scale
- Sense of scale. In everyday terms it is about 3 football pitches across.
Standing on it
- Don't jump. Escape velocity here is only around 0.19 m/s. A determined jump would launch you off it and into your own orbit around the Sun.
By the numbers
- Size. Roughly 316 metres across.
What's in a name
- Designation. Known only by its catalogue designation — no name yet.

Why (169352) 2001 UY16 is an uncommon neo
(169352) 2001 UY16 scores 23 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 11 points would lift it into a rarer tier.
That score comes from 5 science badges — Near-Earth object, Tiny fragment (<1 km), Catalogue designation only, Apollo: crosses Earth's orbit 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.
