Trivia

What makes it special

  • Trojan. Locked in a gravitational sweet spot 60° ahead of or behind a much larger body, shepherded there for billions of years.

What it actually is

  • Its orbit family. A Jupiter trojan, parked in a gravitational sweet spot 60° ahead of or behind Jupiter and shepherded there for billions of years. There may be as many trojans as there are main-belt asteroids.
  • Closest approach. At its nearest it comes within 4.53 AU of the Sun — inside the orbit of Jupiter.
  • One lap. A single orbit around the Sun takes it about 11.9 years.
  • How far it roams. Its orbit swings between 4.53 and 5.88 AU from the Sun.

Sense of scale

  • Sense of scale. In everyday terms it is roughly 5.2× the height of Mount Everest.
  • Walk around it. Walking its equator at a steady pace, eight hours a day, would take about 3.6 days.

By the numbers

  • Size. Roughly 45.8 km across.

How to see it

Like any astronomical target, (20424) 1998 VF30 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 (20424) 1998 VF30 is a common asteroid

(20424) 1998 VF30 scores 19 points on Spacedle's rarity scale, which places it in the common tier. Another 3 points would lift it into a rarer tier.

That score comes from 4 science badges — Asteroid, Trojan, Notably bright (low H) and Catalogue designation only — 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.
