Planets
This is the closest planet to the sun
MERCURY
The force that keeps planets orbiting the Sun.
GRAVITY
The Gallaudet Eleven helped scientists from this U.S. space agency learn about motion sickness and balance.
NASA
How many planets are in our solar system?
This planet is known as Earth's twin because it is similar in size.
VENUS
A scientist who studies space is called this.
ASTRONOMER
These students all attended this university for Deaf and hard of hearing students in Washington, D.C.
GALLAUDET UNIVERSITY
The Moon's gravity is about one-sixth of Earth's. Because of this, astronauts can do this more easily.
JUMP
This is the largest planet in the solar system.
JUPITER
Earth takes this long to orbit the Sun.
ONE YEAR
The Gallaudet Eleven were chosen because being Deaf made them less likely to get this problem in space.
MOTION SICKNESS
This astronaut was the first person to walk on the Moon.
Neil Armstrong
This planet has the most visible ring system.
SATURN
A rock from space that survives and reaches Earth's surface is called this.
METEORITE
Scientists were interested in the Gallaudet Eleven because damage to this part of the inner ear made them unusually resistant to motion sickness.
(INNER EAR BALANCE SYSTEM)
The first living creature to orbit Earth was a dog with this name.
This planet takes about 165 Earth years to orbit the Sun once.
NEPTUNE
The Milky Way is this type of system.
GALAXY
Clue: The Gallaudet Eleven weren't chosen simply because they were Deaf. They were chosen because many of them had become Deaf from this childhood illness, which also damaged their balance organs.
MENINGITIS
This was the name of the first mission that landed humans on the Moon.
APOLLO 11
