Space & astronomy
Planet sizes, orbital distances, light travel time and what you would weigh elsewhere.
- Cosmic timeline A moment in cosmic history against the Big Bang, the first stars and the formation of Earth.
- Distances in space A distance against orbits, the Moon, the outer planets and the nearest stars.
- Escape velocity Escape velocity from each planet, moon and star, against speeds you already know.
- Jumping on other worlds A standing jump recalculated for the gravity of each planet and moon.
- Light travel time Light travel times from the Moon, the Sun, the planets and the nearest galaxies.
- Orbit altitudes An orbital altitude against the ISS, imaging satellites, GPS and geostationary orbit.
- Planet sizes Every planet drawn to the same scale, with the Sun and the Moon for reference.
- Rocket sizes A rocket height against Falcon 9, the Saturn V, Starship and the Statue of Liberty.
- Satellites in orbit A satellite count against the constellations now in orbit and the debris around them.
- Scale model solar system The solar system shrunk to a walkable scale, with every planet’s distance and size.
- Star sizes Stellar diameters from white dwarfs to hypergiants, with the Sun and Earth for scale.
- Temperatures in space A temperature against space, the planets, the Sun’s surface and its core.
- Weight on other planets Your weight recalculated for the surface gravity of every planet, the Moon and the Sun.
