Trivia

What it actually is

  • Its orbit family. An Amor-class object. It approaches Earth's orbit from outside without ever crossing it — named for the asteroid Amor, which swept past at 16 million km in 1932.
  • Closest approach. At its nearest it comes within 1.09 AU of the Sun — inside the orbit of Mars.
  • One lap. A single orbit around the Sun takes it about 3.7 years.
  • How far it roams. Its orbit swings between 1.09 and 3.71 AU from the Sun.

Sense of scale

  • Sense of scale. In everyday terms it is roughly 0.4× the height of Mount Everest.

By the numbers

  • Size. Roughly 3.6 km across.

What's in a name

  • Designation. Known only by its catalogue designation — no name yet.

Why (5587) 1990 SB is a trash neo

(5587) 1990 SB scores 13 points on Spacedle's rarity scale, which places it in the trash tier. Another 2 points would lift it into a rarer tier.

That score comes from 4 science badges — Near-Earth object, Catalogue designation only, Amor: shadows Earth's orbit from outside 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.
