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 0.52 AU of the Sun — inside the orbit of Venus.
  • One lap. A single orbit around the Sun takes it about 1 years.
  • How far it roams. Its orbit swings between 0.52 and 1.52 AU from the Sun.

Sense of scale

  • Sense of scale. In everyday terms it is about 6 football pitches across.

Standing on it

  • Don't jump. Escape velocity here is only around 0.38 m/s. A determined jump would launch you off it and into your own orbit around the Sun.

By the numbers

  • Size. Roughly 630 metres across.

Its orbit genuinely intersects Earth's track around the Sun. The two paths cross; only the timing keeps them apart.

How to see it

Like any astronomical target, (250458) 2004 BO41 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.

Why (250458) 2004 BO41 is a common neo

(250458) 2004 BO41 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, Tiny fragment (<1 km), Crosses Earth's orbit, Catalogue designation only and Apollo: crosses 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.
