✨ 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 1.24 AU of the Sun — inside the orbit of Mars.
- 🔁 One lap. A single orbit around the Sun takes it about 4.3 years.
- 🥏 How far it roams. Its orbit swings between 1.24 and 4.09 AU from the Sun.
Sense of scale
- 🧱 Sense of scale. In everyday terms it is roughly 4.3× the height of Mount Everest.
- 🚶 Walk around it. Walking its equator at a steady pace, eight hours a day, would take about 3 days.
By the numbers
- 📐 Size. Roughly 37.7 km across.
What's in a name
- 🏷️ Named. Notable enough to have earned a proper name, not just a catalogue number.

About Ganymed
Ganymed is an uncommon neo. It has spectral type S and swings within 1.243 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, Ganymed 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. The visibility panel above works out tonight's viewing window for your saved location.
Why Ganymed is an uncommon neo
Ganymed scores 29 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 5 points would lift it into a rarer tier.
That score comes from 5 science badges — Near-Earth object, Notably bright (low H), Has a proper name, Amor: shadows Earth's orbit from outside and Stony asteroid — 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.
