basic space stuff
List the planets from closest to farthest from the sun
mercury, venus, earth, mars, jupiter, saturn, uranus, neptune
Facts about Neptune
farthest from the sun, -218 degrees celsius to -200 degrees celsius, found on september 23 1846, has 6 rings, cannot be seen with the naked eye, 14 moons, 8th planet
What is a comet
comets are space bodies made of ice, dust, and small rocks. There almost the size of a small town. They orbit the sun but when they get to close they melt which makes tails that stretch millions of miles behind them.
whats the first and second phase of the moon
1. new moon 2. waxing crescent
what emits light
stars and the sun emit light
what is the biggest planet
jupiter
facts about earth
4.5 billion years old, known as terra, 2 types of crust; oceanic and continent, only planet that can support life, rocky planet, covered mostly in water, 3rd planet
what is an asteroid
asteroids are small planets that orbit the sun. they are rocky and dont have a particular shape. in diameter theyre about a few meters but there hundreds of kilometers.
whats the third and fourth phase of the moon
3. first quarter 4. waxing gibbous
what reflects light
the moon, planets, comets, asteroids, meteoroids
all the gas giants
jupiter, saturn, uranus, neptune
Facts about jupiter
high of -100 degrees celsius low of -160 degrees celsius, 75 moons, 746.32 million km from the sun largest planet, discovered in 1610, brown orange red and white, biggest planet, 5th planet
what is a meteoroid
they are objects in space that are between the size of a grain of dust to a small asteroid. When they come into the earths atmosphere at high speed they will burn up and we seem them as shooting stars. theyre made when peices of asteroids and comets break off. since their no longer in the suns orbit earths gravity pulls them towards us. their the only exception to objects that make their own light.
whats the fifth and sixth phase of the moon
5. full moon 6. waning gibbous
lifecycle of a star
stars start out in a giant cloud of dust called nebulae. it starts to heat up. when its hot enough the star is formed. the star burns for billions of years. once the star runs out of hydrogen it becomes red and expands. the core will make iron and eventually the star will collapse.
phases of the moon in order
new moon, waxing cresent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter, waning cresent,
How many moons does neptune have and what does the temp range from? How many moons does jupiter have and what does the temp range from?
neptune has 14 moons and the temp ranges from -218 to -200. jupiter has 75 moons and the temp ranges from -100 to -160
what are the stages of a meteorite
a chunk of a comet/asteroid comes off which is a meteoroid, gets pulled by earths gravity and starts burning which is meteor, if it makes it to the ground without fully burning up it is called a meteorite
whats the seventh phase of the moon
7. last quarter
what are the different types of stars
the two different types of stars are the brown dwarfs and the giant stars
all the rocky planets
mercury, venus, earth, mars
When were the 3 planets found
Neptune: September 23 1864
Jupiter: 1610
Earth: more than four billion years old
how many known comets are their? how many knwon asteroids are there?
3,500 comets. 794,600 asteroids
whats the last phase of the moon
8. waning crescent
how can we see bodies that reflect light
we see them because they reflect the light from objects that emit light and we see the parts that are being reflected. Planets cant reflect light but we see them because they are reflecting light from the sun or other light emitting objects
