00:0-1	we are going to learn about a massive star in
00:03	the center of our solar system . What is it
00:06	called ? Yeah , the Sun actually , the Son
00:10	is the only star in our solar system . But
00:13	still it is huge . It is bright and without
00:16	it life on earth wouldn't exist . So it is
00:19	super important . But let's start here . The first
00:24	fact about the sun we want to learn is that
00:26	the sun is just a regular star . That's right
00:29	. It's just a regular star . There are hundreds
00:33	of billions of stars in our galaxy called the Milky
00:37	Way galaxy . But the sun is special to us
00:40	, right ? Because it is in the center of
00:42	our solar system . But the sun really is a
00:45	regular star . Like other stars , the sun uses
00:50	hydrogen to burn bright hydrogen is the sun's fuel just
00:55	like food is our fuel , and gasoline is the
00:58	fuel used by cars . The Son uses hydrogen as
01:02	fuel . If you're wondering what hydrogen is , hydrogen
01:07	is a gas found all over our universe , and
01:11	it's hard to see because it doesn't have any color
01:13	to it , but it's all over the place .
01:15	In fact , hydrogen is the most common element in
01:19	our universe . So stars use a gas called hydrogen
01:23	as fuel . The larger the star , the faster
01:27	it burns through hydrogen , thankfully the sun has at
01:30	least a five billion year supply of hydrogen left ,
01:34	so the sun will keep burning for a long time
01:39	. Here's an interesting question . How far is Earth
01:42	from the sun ? How far is our planet from
01:47	this huge star in the center of our solar system
01:52	? Well , it's pretty far away , it's pretty
01:54	far away . The sun is about 93 million miles
01:58	away from Earth . That's right , about 93 million
02:03	miles away from our planet earth . And it's a
02:07	good thing . It's a great thing that the sun
02:09	is about 93 million miles away because if we were
02:13	any closer to the sun , it would be way
02:15	too hot to sustain life . And if we were
02:18	further away we would all freeze , it would be
02:21	way too cold . So the sun is the perfect
02:24	distance away from the earth . Of course , having
02:28	a huge star 93 million miles away helps us to
02:32	see things right . It is helpful to have a
02:34	massive burning light in the middle of our solar system
02:38	that runs on hydrogen . I mean , can you
02:40	imagine living in a world without light , it would
02:45	be like this , This is what our world would
02:48	be like without sunlight , it would just be dark
02:51	. You know , we wouldn't be able to see
02:52	anything , We'd be like bumping into each other and
02:54	to be crazy , would be like , oh wow
02:57	, is that a mountain or is that a chicken
02:59	or what's going on ? Where am I what's going
03:04	on ? The sunlight allows our eyes to see what's
03:08	going on around us . But the sun provides more
03:13	than just sunlight . The sun provides energy . One
03:17	powerful way the sun provides energy is through a process
03:20	called photosynthesis , wow , that's a big word .
03:23	Can you say that with us ? Photosynthesis ? Yeah
03:28	, photosynthesis , photosynthesis is how plants make plant food
03:33	and produce oxygen without sunlight , Plants cannot make plant
03:39	food or release oxygen . You know plants are not
03:44	alone in using sunlight for energy . We use sunlight
03:48	for energy as well . The energy we get from
03:51	sunlight is called solar energy . Just like plants capture
04:01	sunlight in the process of photosynthesis . People capture sunlight
04:05	using these things called solar panels . Isn't that cool
04:10	? Mhm . Yeah , here are two men installing
04:13	solar panels . The sun is powerful . It is
04:16	awesome to see how we can use some of its
04:19	energy to get power and electricity . Mhm . It
04:24	has been so much fun learning about the sun with
04:27	you . We learned that the sun is the only
04:32	star in our solar system . Do you remember where
04:36	in our solar system the sun is ? Uh huh
04:40	. Right in the middle . Yeah , Like other
04:44	stars , it uses hydrogen as fuel thankfully it has
04:48	a lot of hydrogen so it will keep burning and
04:52	burning for a long time . We learned that the
04:54	sun is about 93 million miles away , which is
04:58	actually the perfect distance . If the sun was further
05:01	away it would be too cold . If it was
05:03	closer , this planet would be way too hot .
05:09	We also learned that the sun not only provides light
05:13	, it brings energy plants use energy from the sun
05:17	in a process called photosynthesis . And people get energy
05:21	from the sun using things like solar panels . Energy
05:25	from the sun is called solar energy . The Sun
05:31	a regular star , but it is special to us
05:36	. It's our Star . Mhm Special thanks to our
05:44	patrons who make these videos possible if you would like
05:47	to help us and also get some cool homeschool pop
05:49	tattoos , click the link below the video or visit

05:56	always . You are so awesome . Thanks for learning
05:58	with us .
