Space Now - Real-time Solar System with 526k asteroids and all tracked satellites

Space Now is a real-time 3D visualization of our solar system, featuring 526,000 asteroids and 35,164 satellites and spacecraft. It includes 837 solar system bodies, from planets and moons to dwarf planets and comets, with accurate orbits from CelesTrak. Users can explore the heliosphere, Kuiper Belt, and Oort Cloud, and track constellations like Starlink and OneWeb. The interactive interface allows drag-to-rotate, zoom, click for info, and fly-through navigation with WASD controls. It's an educational and awe-inspiring tool for space enthusiasts, offering a comprehensive view of near-Earth objects and space debris.

Drag to rotate, wheel to zoom, click for info and orbit, double-click to fly to a body. WASD to fly, R/F up/down, Q/E and arrows to turn, Shift for speed. Click a group name to highlight it, 👁 for orbits.

    Oh man, it seems like my asteroid (Minor Planet 31689 - Sebmellen [0]) is missing.

    Author here. It's a browser view of the Solar System at real scale, with its current state, plus the objects around Earth from the CelesTrak catalog.

    Data: CelesTrak TLEs (SGP4), asteroids and comets from JPL SBDB, spacecraft positions from JPL Horizons. Updated daily.

    Rendering is WebGL2, orbit propagation runs in web workers. The asteroid set (~30 MB) loads in the background.

    The time slider runs forwards and backwards; satellites appear and disappear by launch date.

    Just spent a little time following Europa Clipper, it will fly by Earth very soon! If you zoom out from Earth, it's already pretty close. This will be its second gravity assist after Mars. Very cool site!

    Celestia did all of this and more. 10+ years ago.

    Beautiful site. I love how tranquil the scene becomes when satellites and spacecraft is unchecked. Thanks for that SpaceX (and others).

More from this day
