Venus is closest to earths planet size.
why does earhs position in the milky way galaxy help protect life
1. round the Sun. 2. following the Sun round the Galaxy.
The Milky Way, parts of which we can see from Earth curving around us.
I don't really like milky ways. Reese's cups are better.
if the Milky way galaxy has roughly 100 billion stars in it like scientist believe. and the odds of this happning are one in one million. when you do all the math it works out to be 10000 earths in our solar system. but that's only if there really is one earth in a million stars. its almost impossible to know for certain
The Sun is classified as a medium to medium-small yellow star. As stars in our galaxy go, the Sun is, truthfully, about as ordinary as stars get - but it does the job!
The Biggest star is called the VY Canis majoris. The sun is invisible compared to this super giant star. I researched and it said that 7 quadrillion earths can fit in the Great VY Canis Majoris. Known to be the biggest star in our galaxy.
All of the earth's motion is completely determined by gravity: the gravitational pull on the earth by the sun (and the larger outer planets), the gravitational pull of the Milky Way galaxy on the sun, the gravitational pull of our local cluster on the Milky Way galaxy and so on, up the ladder.
Our galaxy is a barred spiral galaxy.
