Explore the current Earth-Moon-object geometry in time, scale, orientation, and stereo order.

Interactive Earth-Moon-object space

Scene reference (UTC): 2026-10-04T19:00:00Z. Positions use retained MPC nominal orbits, not the separate Find_Orb solution in Actual/Small. Start and Reset show an orthographic overview equivalent to about 1,000,000 km at 90 degrees, not a physical Teleport location. Explicit saved view links take priority.

Explore the geometry

Purpose: makes sky direction and distance tangible in freely rotatable, right-handed equatorial J2000 space.

Display: cloud-free NASA Earth, LRO Moon, the real bright-star sky, current objects, and their centre-relative trajectories. Every trail point is the object's position relative to the chosen centre at that same UTC instant.

Read: drag anywhere for unrestricted rotation. Use +/− to zoom, Left/Right for reverse/forward, Up/Down for faster/slower, Home/End for the period boundaries, and Space to start or stop.

Center keeps a moving target in the middle. Teleport moves the observer onto a body or object and hides that observer from its own view.

Hold the left mouse button and drag in either axis to rotate. Left drag orbits around Center; right drag pans without rotation. Teleport selects the reference observer and distance; an orbited view is virtual. Recenter clears panning without changing rotation, target, observer, zoom or UTC. No off-screen edge markers are drawn.
