About (55532) 2001 WG2
(55532) 2001 WG2 is a common neo. It has spectral type Sk and swings within 0.547 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 Apollo-class object: its orbit is wider than Earth's but crosses it. Most known Earth-crossers belong to this family.
- Closest approach. At its nearest it comes within 0.55 AU of the Sun — inside the orbit of Venus.
- One lap. A single orbit around the Sun takes it about 2.4 years.
- How far it roams. Its orbit swings between 0.55 and 3.04 AU from the Sun.
Sense of scale
- Sense of scale. In everyday terms it is roughly 0.1× the height of Mount Everest.
Standing on it
- Don't jump. Escape velocity here is only around 0.79 m/s. A determined jump would launch you off it and into your own orbit around the Sun.
By the numbers
- Size. Roughly 1.3 km across.

How to see it
Like any astronomical target, (55532) 2001 WG2 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 (55532) 2001 WG2 is a common neo
(55532) 2001 WG2 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 5 science badges — Near-Earth object, Crosses Earth's orbit, Catalogue designation only, Apollo: crosses 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.
