Here are some things that travel in space:
Natural Objects:
* Asteroids: These are rocky bodies that orbit the sun.
* Comets: These are icy bodies that orbit the sun. When they get close to the sun, they melt and create a tail of gas and dust.
* Planets: These are large, round objects that orbit a star.
* Moons: These are smaller bodies that orbit a planet.
* Stars: These are giant balls of burning gas.
* Galaxies: These are vast collections of stars, gas, and dust.
Human-Made Objects:
* Spacecraft: These are vehicles designed to travel in space. Some spacecraft are unmanned, like probes that explore other planets. Others are manned, like the International Space Station and the Space Shuttle.
* Satellites: These are artificial objects that orbit the Earth. They have many uses, such as communication, navigation, and weather forecasting.
* Space Debris: This is any piece of human-made object that is no longer in use and is orbiting Earth. It can pose a hazard to other spacecraft.
Energy and Information:
* Light: Light travels at the fastest speed possible, and it carries information from stars and galaxies across the universe.
* Radiation: This is energy that travels in the form of waves or particles. It can be harmful to living things.
So, what travels in space? Pretty much anything you can think of! It all depends on what you mean by "travels".
