✨ 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 0.97 AU of the Sun — inside the orbit of Earth.
- 🔁 One lap. A single orbit around the Sun takes it about 1.9 years.
- 🥏 How far it roams. Its orbit swings between 0.97 and 2.11 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 3.2 km across.
What's in a name
- 🔢 Designation. Known only by its catalogue designation — no name yet.

About (25330) 1999 KV4
(25330) 1999 KV4 is an uncommon neo. It has spectral type B and swings within 0.969 AU of the Sun at perihelion.
Its orbit genuinely intersects Earth's track around the Sun. The two paths cross; only the timing keeps them apart.
How to see it
Like any astronomical target, (25330) 1999 KV4 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. Because it moves against the background stars, the live position panel on this page tracks where it is right now.

Why (25330) 1999 KV4 is an uncommon neo
(25330) 1999 KV4 scores 23 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 11 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 Carbonaceous — as old as the solar system — 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.
