About 2008 SS
2008 SS is a common neo. It swings within 0.484 AU of the Sun at perihelion.
Its orbit genuinely intersects Earth's track around the Sun. The two paths cross; only the timing keeps them apart.

Trivia
What makes it special
- It crosses our path. Its orbit genuinely intersects Earth's track around the Sun. The two paths cross; only the timing keeps them apart.
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 0.48 AU of the Sun — inside the orbit of Venus.
- One lap. A single orbit around the Sun takes it about 327 days.
- How far it roams. Its orbit swings between 0.48 and 1.37 AU from the Sun.
Sense of scale
- Sense of scale. In everyday terms it is about 1.3 football pitches across.
Standing on it
- Sunlight there. At closest approach the Sun beats down about 4.3 times harder than it ever does on Earth.
- Don't jump. Escape velocity here is only around 0.08 m/s. A determined jump would launch you off it and into your own orbit around the Sun.

How to see it
Like any astronomical target, 2008 SS 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 2008 SS is a common neo
2008 SS scores 21 points on Spacedle's rarity scale, which places it in the common tier. Another 1 point would lift it into a rarer tier.
That score comes from 4 science badges — Near-Earth object, Crosses Earth's orbit, Catalogue designation only and Aten: mostly inside Earth's orbit — 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.
