My space report is on Neptune the cold like ice and water like right now its is -215 degrees celsius how would you like that for 41 years hey!yes I said 41 years on summer and winter there is no autum or spring!I think everyone know what its named after Neptune the king on water the little mermaids Dad, Neptune is named after a Roman god they named it that because it looks blue,Neptune does have water but very little of it here are the gases 3.2% hydrogen,3.2% helium,0.5% methane,0.019% hydrogen deuteride,0.00015% ethane all of its gases together make it absorb red light wich make it look like a lovely blue so hight thin clouds drift to the atmosphere these are the ices:ammonia,water,ammonium hydrosulfide,methane ice.It is4,495,000,000 million kilometers from the sun. It takes 5,840 hours to revolve around the sun and 16 hours to spin,It ways 102,400,000,000,000,0 thousand Neptune has 14 moons and some have water/ice on them on our moon you cant last one night on it is so coldand its diameter is 49.529 kilometers it is the smallest of the ice giants.Every thing has a age Neptune is 4,503 years old ,well every planet is that old and only be seen though a telescope and has 8 faided rings they are made of ice and seem to be invisiblethat they are so small.Its was disscoverd in september 23rd 1864 by Urbain Le Verrier and Johann Galle.Only one space craft has been to Neptune in 1989 the Voyager 2 spacecraft swept past the planet.It returned the first closeup images of the Neptune system.Neptune is similar in composition to Uranus, and both have compositions that differ from those of the larger gas giants , Juptier and Saturn. Neptune's atmosphere, like Jupiter's and Saturn's, is composed primarily of hydrogen and helium , along with traces of hydrocarbons and possibly nitrogen; it contains a higher proportion of "ices" such as water, ammonia, and methane. Scientists sometimes categorise Uranus and Neptune as "ice " to emphasise this distinction.11 The interior of Neptune, like that of Uranus, is primarily composed of ices and rock.12 Traces of methane in the outermost regions in part account for the planet's blue appearance.
In the video we watched was a Bill Nye one, I love the Bill Nye show its about science and space.In this video he was talking about space and our solar system, he showed us how far the nearest star would be if the sun was smaller.we also learned that light travels at 300,000,0 kl per second its the fastest thing on earth.Some meteors are the size of a grain of sand and 10 tons of them hit the earth every day!!!I now know that we are made of the same things as stars its pretty cool.id you know that a light year is about 9.5 trillion years!Now you know!!!!!Is it cool that you can`t get to the nearest star even if you tried your whole life!A constellation is a group of star we have given a name like the little dipper and the big dipper and our north star polarise is part of the little dipper!We can learn about space by looking at stars and look at planets every day.The earth has a circumference,it is how big the earth wich is 6,371 km.
1.What is gravity?
Gravity is a force pulling you down here's a ex. when you hop or jump on a trampoline the force of gravity pulls you down all the planets have gravity even the moons have it gravity.Gravity is also gravitational pull its pulls us down.If there was no gravity we would be floating every where,there would be no day or night or seasons
2.Describe the position,motion and comonents of our solar system?
The position of our solar system is in the milky way.we rotate to the left so we get day and night.The gravity is one of the things that contain our galaxy to stay together.The universe is special to us its what keeps us in our solar system and all the other planets too.We rotate around the sun and the sun very slowly rotates around the milky way ,the milky way is not be to a nebula nebulas have to be about 300,000,000,000,000,000,000,000,0 stars or bigger.Black holes are to suck up planets or galaxys a day FACT: there could be rainbows in space
3.facts on earth
the earth is 4.543 billion years old.Every thing is made of stardust true.If earth lost air for five seconds we would die!

Equatorial Circumference: 40,030 km
Known Moons: 1
Notable Moons: The Moon
Orbit Distance: 149,598,262 km (1 AU)

4.Compare the environment of earth V.S your planet
Earth has land trees water and every thing we need to live but Neptune has no resources for things to like or so think.On earth winter is three months but on Neptune its 41 YEARS!Yes I said years.Earth has one gas the covers the planet its is air On Netune the gas is blue and no air at all if we try to breath we would die.
