Click an event to jump there. "Coming up" is calculated from this model for the two years after the date shown, and is accurate to about a day. Planets never line up exactly; conjunctions are when two appear close together in our sky.
Distances are true. Each planet and its moon system is enlarged together by this factor, and the Sun by at most 20×. At 1× everything is true size. Bodies too small to see appear as dots.
By default, sizes and distances are compressed so everything fits; tick True scale to see real distances. Directions and timing are always real. Poles shows each body's spin axis: the arrow marks the end it turns anticlockwise around, and the ring its equator. Earth turns in real time, so daylight and city lights fall where they really are right now. The background shows the real stars to magnitude 6 in their true directions.

Moon orbits and positions are fitted to JPL's ephemerides for 1960–2060, including their tilts and precession (within a few degrees; less accurate outside that range). Earth's Moon and Jupiter's four large moons use dedicated theories.
