✨ 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 8219 megatons — about 164 times the largest bomb ever detonated.
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 1.03 AU of the Sun — inside the orbit of Mars.
🔁One lap. A single orbit around the Sun takes it about 2.7 years.
🥏How far it roams. Its orbit swings between 1.03 and 2.8 AU from the Sun.
Sense of scale
🧱Sense of scale. In everyday terms it is about 4.8 football pitches across.
Standing on it
🦘Don't jump. Escape velocity here is only around 0.3 m/s. A determined jump would launch you off it and into your own orbit around the Sun.
