Larissa (moon)

Larissa is a moon that orbits the giant blue planet Neptune. It's not a round, smooth ball like our Moon. Instead, Larissa looks more like a lumpy potato or a giant rock! It's a very small moon, much smaller than Earth's Moon. Imagine a tiny pebble compared to a big beach ball. Larissa is made of ice and rock, and it's a bit of a bumpy ride around Neptune.

Larissa zips around Neptune super fast! It takes less than one Earth day for Larissa to complete one trip around its planet. That's faster than you can go to school and come back! Neptune itself is a huge planet, so Larissa has to travel quite a distance to go all the way around. It's like a tiny race car zooming around a giant playground.

This little moon is made of a mix of ice and rock. It's not a cozy place to visit because it's very cold and there's no air to breathe. Scientists think Larissa is made of the same stuff that Neptune is made of, but it's much, much smaller. It's like a tiny piece that broke off from a much bigger puzzle a long, long time ago.

Larissa was discovered a long time ago by people looking through big telescopes. It's one of Neptune's inner moons, meaning it's closer to Neptune than some of its other moons. Because it's so close, it looks quite big in the sky from Neptune, even though it's small. It's like seeing a tiny ladybug up close – it seems bigger than it really is!
