Trivia
What it actually is
- Closest approach. At its nearest it comes within 1.74 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.
- Steeply tilted. Its orbit is tipped 64° out of the flat plane the planets share — it spends most of its time well above or below them.
- 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 0.6× the height of Mount Everest.
Standing on it
- Sunlight there. Even at its closest the sunlight is only about 33% as strong as Earth's.
By the numbers
- Estimated size. Nobody has measured its size directly. Assuming it reflects light like a typical asteroid, its brightness implies something roughly 5.5 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/2010 LN135 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/2010 LN135 is a rare asteroid
A/2010 LN135 scores 49 points on Spacedle's rarity scale, which places it in the rare tier. Another 1 point would lift it into a rarer tier.
That score comes from 6 science badges — Asteroid, Wildly elliptical orbit, Unbound (hyperbolic) orbit, Catalogue designation only, Hyperbolic comet (one pass, then gone) 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.
