No astronaut has travelled to a different planet. If they were to do so it would be for exploration and exploitation. Astronauts are known to explore and travel for the benefit of the others.
The speed of planets will vary as they travel at different speeds. Mercury is the fastest planet while Pluto is the slowest. The speed of the planets is influenced by how close they are to the sun.
Inner planets travel faster than outer planets
That depends on the planet. Gravitation on different planets varies. On planet Earth, you multiply by 9.8; the result is in Newtons.
smd thats what the answer is stah huh ? copy 'k
yes they all travel in an orbit
you explore space and different planets.
astronaut
Well they travel to different places such as the moon,and they travel to explore different planets.
Dennis Tito was the first astronaut to travel to the planet Venus.
to explore many different planets, galaxies, comets, possible planets we can live on, etc.
The planets travel around the sun.
It was Johannes Kepler who produced the theory of the planets' positions and speeds which is accepted today.
Planets travel in elliptical orbits.
Pedro Duque was the first astronaut in space.
how far planets are each other and where they are . :)
