Trivia
Hard to believe
- Against the traffic. It goes round the Sun backwards, against the direction every planet and almost everything else travels.
What it actually is
- Closest approach. At its nearest it comes within 3.72 AU of the Sun — inside the orbit of Jupiter.
- One-way trip. On a hyperbolic path — it will leave the Solar System and never return.
- Ancient. A leftover from the Solar System's birth, older than every continent on Earth.
Sense of scale
- Sense of scale. In everyday terms it is roughly 0.3× the height of Mount Everest.
Standing on it
- Don't jump. Escape velocity here is only around 1.65 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 2.7 km across.
What's in a name
- Designation. Known only by its catalogue designation — no name yet.

How to see it
Like any astronomical target, A/2024 W2 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 A/2024 W2 is an epic asteroid
A/2024 W2 scores 53 points on Spacedle's rarity scale, which places it in the epic tier. Another 25 points would lift it into a rarer tier.
That score comes from 6 science badges — Asteroid, Retrograde orbit, Wildly elliptical orbit, Unbound (hyperbolic) orbit, Catalogue designation only and Hyperbolic comet (one pass, then gone) — 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.
