The Sun is the only star in our solar system, which means it is the sole source of energy for Earth. Its immense gravitational pull keeps the planets, including Earth, in orbit, allowing for a stable environment. The Sun generates energy through nuclear fusion, releasing light and heat that sustain life on our planet. Other stars are too far away to have any significant impact on Earth's energy or climate.
What else can I help you with?
Why isn't a galaxy size alone useful in determining its distance from earth earth?
The only thing that can be directly observed is a galaxy's apparent size (angular size). Since galaxies come in different sizes, this can only give a rough idea of the galaxy's distance from Earth.
Why is the sun the only star in your galixy that suplies energy to the earth?
The Sun is the only star in our solar system, providing energy to Earth due to its proximity and unique characteristics. Its immense gravitational pull keeps the planets in orbit, while its nuclear fusion processes generate light and heat essential for life. Other stars in our galaxy are too far away to significantly impact Earth's energy balance. Thus, the Sun is the primary source of energy that sustains our planet's climate and ecosystems.

How many earths can fit into the milkyway galaxy?
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
True or false the Milky Way is the only galaxy in the universe?
Our Sun and the planet Earth (Along with all the other planets and other stellar stuff) comprise the Solar System. Our Solar System is part of the Milky Way Galaxy.See related question for our position in the Galaxy

How many earths are in each galaxy?
there is only 1 earth
What galaxy is gliese581g in?
Gliese581g is in the Milky Way Galaxy. It is "only" 20.5 light years away from Earth.
Is the earth a galaxy?
...only as a metaphor. The Earth is a planet that is in the Milky Way galaxy. The Earth is not a galaxy. No, the Earth is a planet which orbits the Sun (which is a star) along with several other plants, this is called the solar system. Our Sun and its planets along with millions of other stars form a galaxy called The Milky Way.

How far is Andromeda galaxy from the Sun?
About 2.5 million light years from Earth, but since the Earth and Sun are only 8 light minutes apart, there isn't that much of a difference in how far the Andromeda Galaxy is from the Sun or Earth. So the Andromeda Galaxy is about 2.5 million light years from the Sun and Earth.
What else besides mitochondria supplies energy to the cell?
The mitochondria in a cell basically creates energy (ATP) from nutrients absorbed through the cell membrane. This is the only organelle that supplies/ creates energy for the cell.

How would you describe the Milky Way galaxy and our place in it?
its a spiral galaxy and the earth is so far the only planet in the milky way where we know we can live
How many people in the galaxy?
Well, you say galaxy, you mean earth, because we are probably the only people in the galaxy, so I would say around 6 billion to 7 billion and counting.
Why is the earth the only planet around your galaxy that has oxygen?
That's a ridiculous question. Why would anyone think earth is unique in this way?
