What's up guys welcome back to another blog post. In science, we have been learning and researching about the solar system and stars. Do you know how stars die? or what is a star?. Well lucky for you I am going to be talking and sharing some facts and peace of information about the solar system and stars. If you have any other facts about stars and the solar system feel free to leave a comment in the comments. Thank you for reading my blog post.
Here is my work
What is a solar system?
A solar system is planets around a star. The planets are in order from closest and farthest away from the sun, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. The solar system is also filled with stars and asteroids, But stars can only be seen at night when it's dark. The sun is a very important part of the solar system because its force of attraction holds the solar system together, and it also gives us light and heat during the day and night.
What is a milky way?
The milky way is shaped like a spiral and it contains up to about 100 - 400 billion stars which also includes the sun. The sun is the only star we see in the day because it provides us with light and heat, and the rest of the stars we see at night. The milky way is a galaxy that our solar system is part of. So the little light we see at night is the billions of stars that are part of the milky way. The milky way doesn’t stay still, it moves around the solar system just like the sun and moon.
What is a star? Describe a Nebula?
A star is a luminous ball of gas, in the olden days stars us to help people navigate seas, and also helps scientists navigate the universe. So a star is huge from where we are. It's really small but up close it's huge. A star is mostly filled with hydrogen and helium that makes light and heat. The little dots that we see at night are years away from earth. They are like little blocks of the galaxy creating all kinds of shapes and pictures. A Nebula is a giant cloud of dust and gas in space. Some of the Nebula is formed by gas and dust from exploding stars that have died.
How does a star die?
It takes millions of years for a star to die but When a star dies it explodes and it expands to form ( A red giant) and then all of its layers will gradually blow into space leaving little white stars called dwarf stars which are about the size of the earth. Stars are born and formed by the dust from clouds in space and can live up to 10 million years, which is like 10x longer than how we live. Without dust and gas stars would not form.
