Sunlight takes about eight minutes and twenty seconds to reach Earth, so we always see the Sun slightly late.

Step 1
Watch them move
Mercury laps the Sun in seconds while Neptune barely creeps along — exactly like the real thing, just sped up.
-
Step 2
Pause the sky
Freeze every orbit with one button so younger explorers can point at a planet without chasing it.
-
Step 3
Change the tempo
Switch between half, normal and double speed to compare how long each planet's year really is.
-
Step 4
Open a planet file
Tap a world to slide open its panel: size, distance, temperature, moons and facts written for kids.
Eight worlds, eight planet files
Prefer a list to a moving map? Every planet card opens the same detail panel with stats, colours, atmosphere and three facts worth remembering.
8planets, each with its own illustrated file and three facts to take away.
