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 1.01 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 1.01 and 1.95 AU from the Sun.
Sense of scale
- Sense of scale. In everyday terms it is about 4.5 football pitches across.
Standing on it
- Don't jump. Escape velocity here is only around 0.28 m/s. A determined jump would launch you off it and into your own orbit around the Sun.
By the numbers
- Size. Roughly 469 metres across.
What's in a name
- Designation. Known only by its catalogue designation — no name yet.

Why (154807) 2004 PP97 is a common neo
(154807) 2004 PP97 scores 21 points on Spacedle's rarity scale, which places it in the common tier. Another 1 point 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 Barely turning (over 100 hours) — 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.
