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 1.02 AU of the Sun — inside the orbit of Mars.
  • One lap. A single orbit around the Sun takes it about 1.2 years.
  • How far it roams. Its orbit swings between 1.03 and 1.28 AU from the Sun.

Sense of scale

  • Sense of scale. In everyday terms it is about 3.3 football pitches across.

Standing on it

  • Don't jump. Escape velocity here is only around 0.21 m/s. A determined jump would launch you off it and into your own orbit around the Sun.

By the numbers

  • Size. Roughly 346 metres across.

What's in a name

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

About (415711) 1998 WT7

(415711) 1998 WT7 is a common neo. It swings within 1.025 AU of the Sun at perihelion.

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.

How to see it

Like any astronomical target, (415711) 1998 WT7 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 (415711) 1998 WT7 is a common neo

(415711) 1998 WT7 scores 17 points on Spacedle's rarity scale, which places it in the common tier. Another 5 points would lift it into a rarer tier.

That score comes from 5 science badges — Near-Earth object, Tiny fragment (<1 km), Catalogue designation only, Amor: shadows Earth's orbit from outside and Steeply tilted orbit (i > 40°) — 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.
