✨ 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 1402 megatons — about 28 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 0.71 AU of the Sun — inside the orbit of Venus.
🔁One lap. A single orbit around the Sun takes it about 330 days.
🥏How far it roams. Its orbit swings between 0.71 and 1.15 AU from the Sun.
Sense of scale
🧱Sense of scale. In everyday terms it is about 2.7 football pitches across.
Standing on it
🦘Don't jump. Escape velocity here is only around 0.17 m/s. A determined jump would launch you off it and into your own orbit around the Sun.

About (208023) 1999 AQ10
(208023) 1999 AQ10 is an uncommon neo. It has spectral type S: and swings within 0.714 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, (208023) 1999 AQ10 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.

The visibility panel above works out tonight's viewing window for your saved location.
Why (208023) 1999 AQ10 is an uncommon neo
(208023) 1999 AQ10 scores 29 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 5 points would lift it into a rarer tier.
That score comes from 5 science badges — Near-Earth object, Potentially hazardous, Catalogue designation only, Aten: mostly inside Earth's orbit and Stony asteroid — 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.
