Solar System Explorer: from Earth's surface to the edge of the universe

Controls

Drag: Orbit around the target
Scroll / pinch: Zoom, from a few km up to the whole universe
Right-drag / Shift+drag: Look around (tilt toward the horizon; away from a black hole)
Click: Fly to a body or a label
Double-click / C: Re-centre the view
Space: Pause time
, . B N: Slower, faster, reverse, now
0–9: Sun, Mercury … Neptune, Pluto
R: Solar System overview
T: Grand Tour (← → to step)
O L K: Orbits, labels, constellations
H F: Hide the interface, full screen

Sizes, distances and orbits are to scale; positions are computed for the date shown.
With "Today's Earth" switched on (Layers), the globe shows NASA's real daily satellite mosaic for the date on the clock — the actual clouds, weather and sea ice — fading to the cloudless high-resolution base as you zoom to street level.
Every star is a catalogued star at its measured distance.
Satellites are propagated live from current orbital elements (SGP4); spacecraft follow real JPL trajectories.
Nebulae, clusters and nearby galaxies sit at their catalogued positions and distances.
Black holes are ray-traced: light is followed through the curved space of a non-rotating hole, so the lensing, the shadow and the Doppler and gravitational shifts of the glowing gas are computed, not painted. Spin is not modelled. The stars orbiting Sagittarius A* follow their measured orbits.
Disc colours are thermal, compressed into the visible range (real discs peak in ultraviolet or X-rays); the orange of Sagittarius A* and M87* follows the radio images.
The belts, the Oort cloud, the cosmic web, the star fields around distant black holes and their host galaxies are statistical models.
