Hello, I'm Jared, and welcome to "Fun Science Demos".
Have you ever stepped outside at night, looked into the sky and
noticed all those little tiny dots of light? Well,
through science we've discovered that almost all of those dots of light
are stars. And the big idea today is that stars
make their own light. Planets like the one we live in,
they actually reflect that light. The closest start to our planet
is the sun, and if the earth were this big,
the sun would be that big.
So let's talk about planets and stars. So which one's the planet
and which one's the star? Well, stars make their own light. Stars are big and they're
made of lots a different gases.
Planets do not make their own light and they're usually smaller
and nice and hard and rocky. I can only see this planet because light
from this star is bouncing off of it. In fact, through science we've discovered
there are eight planets in our solar system and the only reason we can see
is because light from our star, the sun, bounces off of them. So think back to that
All those dots of light, and most of them
are stars. And those stars are really far away
and really, really big. Stars and planets;
science is so cool. Don't forget to check out our links in our video description.
Thanks for watching.
