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 0.68 AU of the Sun — inside the orbit of Venus.
  • One lap. A single orbit around the Sun takes it about 1.7 years.
  • How far it roams. Its orbit swings between 0.68 and 2.18 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 0.64 m/s. A determined jump would launch you off it and into your own orbit around the Sun.

By the numbers

  • Size. Roughly 1.1 km across.

How to see it

Like any astronomical target, (52750) 1998 KK17 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 (52750) 1998 KK17 is an uncommon neo

(52750) 1998 KK17 scores 27 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 7 points 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 Brilliantly reflective surface — 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.
