✨ 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 10.1 thousand megatons — enough to devastate a region the size of a small country.
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 0.29 AU of the Sun — inside the orbit of Mercury.
🔁One lap. A single orbit around the Sun takes it about 243 days.
🥏How far it roams. Its orbit swings between 0.3 and 1.23 AU from the Sun.
Sense of scale
🧱Sense of scale. In everyday terms it is about 5.1 football pitches across.
Standing on it
🔥Sunlight there. At closest approach the Sun beats down about 11.5 times harder than it ever does on Earth.

About 2019 FJ
2019 FJ is an uncommon neo. It swings within 0.295 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, 2019 FJ 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 2019 FJ is an uncommon neo
2019 FJ 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 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.
