✨ Trivia
Handle with care
🛡️What 'hazardous' means. 'Potentially hazardous' is bookkeeping, not a prediction: it means the orbit passes within 0.05 AU of Earth's and the body is big enough to matter. Nothing on that list is known to be on a collision course.
☄️If it ever hit. A rock this size arriving at a typical 20 km/s would release around 2695 megatons — about 53.9 times the largest bomb ever detonated.
What it actually is
🛸Its orbit family. An Aten-class object, spending most of its time inside Earth's orbit and crossing ours from the sunward side — which makes this family wretchedly hard to spot against the daylight.
🌞Closest approach. At its nearest it comes within 0.41 AU of the Sun — inside the orbit of Venus.
🔁One lap. A single orbit around the Sun takes it about 276 days.
🥏How far it roams. Its orbit swings between 0.41 and 1.25 AU from the Sun.
Sense of scale
🧱Sense of scale. In everyday terms it is about 3.3 football pitches across.
Standing on it
🔥Sunlight there. At closest approach the Sun beats down about 5.9 times harder than it ever does on Earth.

About (523664) 2012 OD1
(523664) 2012 OD1 is a rare neo. It swings within 0.412 AU of the Sun at perihelion.
An Aten-class object, spending most of its time inside Earth's orbit and crossing ours from the sunward side — which makes this family wretchedly hard to spot against the daylight.
How to see it
Like any astronomical target, (523664) 2012 OD1 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 (523664) 2012 OD1 is a rare neo
(523664) 2012 OD1 scores 43 points on Spacedle's rarity scale, which places it in the rare tier. Another 7 points would lift it into a rarer tier.
That score comes from 7 science badges — Near-Earth object, Potentially hazardous, Tiny fragment (<1 km), Catalogue designation only, Aten: mostly inside Earth's orbit, Brilliantly reflective surface and Steeply tilted orbit (i > 40°) — 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.
