✨ Trivia
What it actually is
- 🛸 Its orbit family. A centaur, wandering between the orbits of Jupiter and Neptune on a path nothing can stabilise. Half asteroid and half comet, and gone from this orbit within a few million years.
- 🌞 Closest approach. At its nearest it comes within 2.28 AU of the Sun — inside the orbit of Jupiter.
- 🔁 One lap. A single orbit around the Sun takes it about 19.6 years.
- 🥏 How far it roams. Its orbit swings between 2.28 and 12.23 AU from the Sun.
Sense of scale
- 🧱 Sense of scale. In everyday terms it is roughly 0.6× the height of Mount Everest.
Standing on it
- 🥶 Sunlight there. Even at its closest the sunlight is only about 19% as strong as Earth's.
By the numbers
- 📐 Size. Roughly 5.4 km across.
What's in a name
- 🔢 Designation. Known only by its catalogue designation — no name yet.
