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 0.67 AU of the Sun — inside the orbit of Venus.
- One lap. A single orbit around the Sun takes it about 2.7 years.
- How far it roams. Its orbit swings between 0.67 and 3.19 AU from the Sun.
Sense of scale
- Sense of scale. In everyday terms it is about 0.4 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
- Estimated size. Nobody has measured its size directly. Assuming it reflects light like a typical asteroid, its brightness implies something roughly 46 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 DG1 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 DG1 is an uncommon neo
2010 DG1 scores 27 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 7 points would lift it into a rarer tier.
That score comes from 4 science badges — Near-Earth object, Catalogue designation only, Apollo: crosses Earth's orbit 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.
