Sun, Moon & Earth Movement Simulator for Perth
Where the sun and the moon are from Perth, at any moment you choose. Today the sun rises at 6:41 AM and sets at 5:57 PM — 11 h 16 m of daylight — and the moon is a waxing gibbous, 98% lit. Drag the slider through a day, a week or a month and watch all of it move.

Perth is the marker on the globe — on the night half at the time shown, riding the dotted circle its spot traces as the Earth turns. The moon is 165° from the sun in the sky then, and that angle is the phase: waxing gibbous. You are looking down on the Earth from far above its orbit, from the south — the side you are on — with sunlight arriving from the top left, so the half of the Earth facing that way is the half having its day. Sizes and distances are not to scale; the directions are.
What Perth’s latitude does to the picture
At 31.9° south, Perth has a moderate swing through the year — 14 h 14 m of daylight at the longest day and 10 h 3 m at the shortest — and the sun never quite reaches straight overhead.
Baked for the moment this page was built; the simulator above recomputes everything in your browser for whatever instant you set.
Why does the Moon change shape? The angle between the Moon and the Sun is the phase.
What is tidal locking? The Moon turns once per orbit, so the same face stays toward us.
The full stack of questions sits on the simulator’s own page.
