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 0.96 AU of the Sun — inside the orbit of Earth.
- One lap. A single orbit around the Sun takes it about 3.8 years.
- How far it roams. Its orbit swings between 0.96 and 3.9 AU from the Sun.
Sense of scale
- Sense of scale. In everyday terms it is about 0.5 football pitches across.
Standing on it
- Don't jump. Escape velocity here is only around 0.03 m/s. A determined jump would launch you off it and into your own orbit around the Sun.
By the numbers
- Size. Roughly 51 metres across.
What's in a name
- Designation. Known only by its catalogue designation — no name yet.

How to see it
Like any astronomical target, 2010 EC43 is best seen from a dark site away from city lights, and when it is above the horizon depends on your latitude and the time of year. Because it moves against the background stars, the live position panel on this page tracks where it is right now. The visibility panel above works out tonight's viewing window for your saved location.
Why 2010 EC43 is a rare neo
2010 EC43 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, Brilliantly reflective surface 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.
