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 0.59 AU of the Sun — inside the orbit of Venus.
- One lap. A single orbit around the Sun takes it about 1.3 years.
- How far it roams. Its orbit swings between 0.59 and 1.74 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 472 metres across.
What's in a name
- Designation. Known only by its catalogue designation — no name yet.

Why (410777) 2009 FD is a rare neo
(410777) 2009 FD scores 41 points on Spacedle's rarity scale, which places it in the rare tier. Another 9 points would lift it into a rarer tier.
That score comes from 6 science badges — Near-Earth object, Tiny fragment (<1 km), Catalogue designation only, Apollo: crosses Earth's orbit, Darker than charcoal and Passes within two lunar distances of Earth's orbit — 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.
