Navigation in space

 Kia Ora readers 

Welcome back to my blog and today here in Hurrumanu 3 we were researching about Navigation in space,and after we research we have to answer the question related to the research.

Here are the questions about the research.

What is a solar system? Our solar system consist our stars,our earth and everything bound to it by gravity the planets Mercury,Venus,Earth,Mars,Jupiter,Saturn,Uranus and Neptune and the solar system controls those planets to go around the sun. What is the milky way an example of?An example of the Milky Way is the galaxy that holds the Solar System in which the Earth is located. The closest large spiral galaxy to the Milky Way is the Andromeda galaxy, which is larger at 220,000 light years across. It is 2.7 million light years away.

What is a star?A star is normally a ball of gas,it is mostly hydrogen and helium,held together by its own gravity. Nuclear fusion in its core support the star against its gravity,and produces photons and heat. Describe a Nebula. A nebula is an a interstellar cloud of dust,Hydrogen,helium and other ionizer gases.How do stars die?The stars die because they ran out of the hydrogen and helium,they ran out of hydrogen and helium because through there lives,stars are fighting against the crushing force of their own gravity. Inside the nuclear reactions fuse together smaller elements to create a bigger energy and because of that the stars were running out of Hydrogen and helium.  

Is there a up and down in space? There is a up and down in space,and down is basically the direction of the gravity pulling you,and the up is just the opposite of the down. How can stars be use to navigate?
