Trivia
Handle with care
- What 'hazardous' means. 'Potentially hazardous' is bookkeeping, not a prediction: it means the orbit passes within 0.05 AU of Earth's and the body is big enough to matter. Nothing on that list is known to be on a collision course.
- If it ever hit. A rock this size arriving at a typical 20 km/s would release around 512.1 thousand megatons — enough to devastate a region the size of a small country.
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 0.25 AU of the Sun — inside the orbit of Mercury.
- One lap. A single orbit around the Sun takes it about 2.5 years.
- How far it roams. Its orbit swings between 0.25 and 3.42 AU from the Sun.
Sense of scale
- Sense of scale. In everyday terms it is roughly 0.2× the height of Mount Everest.
Standing on it
- Sunlight there. At closest approach the Sun beats down about 16.4 times harder than it ever does on Earth.

Why (242643) 2005 NZ6 is a rare neo
(242643) 2005 NZ6 scores 41 points on Spacedle's rarity scale, which places it in the rare tier. Another 9 points would lift it into a rarer tier.
That score comes from 6 science badges — Near-Earth object, Potentially hazardous, Wildly elliptical orbit, Catalogue designation only, Apollo: crosses Earth's orbit and Darker than charcoal — 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.
