An asteroid is a large rock is outer space. Some can be very large, while others can be as small as a grain of sand. Because they are small, they do not have enough gravity to pull themselves into a sphere.
Where are asteroids?
The majority of asteroids are in the Asteroid Belt.
Where is the Asteroid Belt?
The Asteroid Belt is between Mars and Jupiter. It is a giant ring of rocks, or asteroids.
Comets are small, irregularly shaped bodies composed mostly of a mixture of ice, dust, and carbon.
What are the parts of a comet?
There are 3 distinct parts. A nucleus, a coma, and a tail. The nucleus is the solid core, which develops a coma with a tail/s when it is close to the sun. The coma is the is a dusty, fuzzy cloud around the nucleus. The tail extends from the comet and points away from the sun.
Where are comets?
Most comets are in the Kuiper Belt.
Where is the Kuiper Belt?
The Kuiper Belt is way out past the orbit of Pluto.
What is the Kuiper Belt?
The Kuiper Belt is a giant ring around the Sun. Instead of asteroids, it has icy comets instead.
The Oort Cloud is a theoretical "cloud" (sphere) of icy debris that circle the sun at a great distance. The celestial bodies in the Oort Cloud do not all go the same way, they circle the Sun in every direction.
How far is the Oort Cloud from the Sun.
The Oort Cloud is about 13 trillion miles from the Sun, and surrounds the Sun and everything around the Sun.
It is when one celestial body moves into the shadow of another. It requires 3 or more celestial bodies to get aligned in a straight line.
What is a Partial Eclipse?
It happens when only part of the celestial body is covered in shadow. The sun will still shine some light on the said celestial body.
What is a Total Eclipse?
The celestial body is completely covered.
What is a Lunar Eclipse?
It is when the Moon is in the Earth's shadow. The moon will appear differently, since it does not create its own light.
When can a Lunar Eclipse happen?
Only when there is a full moon.
What happens to the Moon's appearance when a Lunar Eclipse happens?
Very often, the moon will appear a deep red or orange colour.
Why does the Moon change it's appearance when a Lunar Eclipse happens?
When there is a Lunar Eclipse, the sunlight first must pass deep through Earth's atmosphere. This filters out most of the blue light from the Sun. The remaining light is reddish, which reflects onto the moon.
What is a Solar Eclipse?
It is when the Earth is in the Moon's shadow.
When can a Solar Eclipse happen?
It can only happen during a New Moon.
What do the Earth, Moon and Sun have to do in order for a Solar Eclipse to happen?
The Earth, Moon and Sun must be in a straight line.
