Navigation In Space - Science [Hurumanu 3]

Hello! In Science, we were tasked to answer the questions that they prepared for us and answer it on our blog or in a google doc. The questions are space related such as the solar system. Like for example, the Mars is part of our solar system

What is a Solar System?

Solar system involves the sun, stars and the planets. The planets are in a specific order. The order is Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. We are the third planet in the solar system which is the earth. The solar system is full of asteroids, comets and meteoroids. There are also many milky ways and galaxies.

What is the Milky Way an example of?

The milky way is an example of a galaxy, and our solar system is part of the milky way.

What is a star?

A star is a glowing ball of gas. It is made from mostly hydrogen and helium. Which are bound together by its own gravity. It is supported by Nuclear fusion reaction against gravity. Producing photons, heat and small particles of denser elements.

Describe a nebula

Nebula is a big cloud of dust and gas, the cause of nebula is the dying star’s explosion. So when the star explodes, it creates a big cloud of dust and gas which is called ‘Nebula’.

How do stars die?

Stars die because they run out of hydrogen, if they run out of hydrogen the star dies and explodes which creates nebulae.

Is there an up and down in space?

There up and down in space. Down is a way of gravity pulling you down. Up is the opposite way.

How can stars be used to navigate?

They can use stars to navigate by finding the 3 separate stars. For example, one of the stars is called the Northern Star. It’s also known as the Polaris star.

Thank you for reading this post, I hope you have learn't something new about navigation in space.
