How would you define 'galaxy'?
'galaxy as a NOUN 1) (with -G-) (a) the luminous area of the night sky containing a huge number of stars; (b) the spiral-shaped disk of matter containing our solar system 2) any of the billions of disks of matter in the universe containing a huge number of stars and possibly planets along with the interstellar medium and dark matter separated by huge voids of space and often centered on a supermassive black hole 3) a particular number of famous, talented, or successful people in a particular field of activity
Is Andromeda the largest galaxy in your solar system?
Andromeda is a fairly large galaxy around 2 million light years away, it's not in our solar system or even in our galaxy. It's a huge separate group of billions of stars, each of which may have solar systems and planets of their own.
Why is the sun a great source of energy?
It provides huge amounts of power, it has done so quite regularly for the last 4 billion+ years, and it will continue doing so for billions of years more.
Is the universe made up of billions of galaxies separated by huge distance?
Lol. No honey the answer is true. :)
Is the universe made up of billions of Galaxy separated of huge distances?

What are the differences between the solar system and the Milky Way Galaxy?
A galaxy - including the Milky Way - is a huge collection of solar systems. Each star is a solar system. A star may or may not have planets, but it is already known that many stars do have planets. A galaxy has hundreds of billions of stars, i.e., hundreds of billions of solar systems.Differences in scale: The nearest star (after the Sun) is Toliman, at a distance of 4.3 light-years - light takes 4.3 years to travel from Toliman to us. That is well outside the Solar System; the farthest objects known in our own Solar System are at a distance of a few light-hours. Our Milky Way, however, has a diameter in the order of 100,000 light-years. It takes light 100,000 years to go across the Milky Way - and there is some reason to believe that nothing can travel faster than light.
What is the difference between a galaxy and the uninerse?
The Universe is everything, as far as we know. A galaxy is just a collection of stars. A galaxy is huge - typically about 100,000 light-years across - but the visible Universe contains hundreds of billions of galaxies.
What is the Milky Way and how is it related to the solar system?
The Milky Way is a huge collection of somewhere between 200 and 400 billion stars, most of which are believed to have planets. Our Sun is one of those stars, and our Solar System is one of those billions of solar systems.The main part of the Milky Way has a diameter of about 100,000 light-years. This means it takes light 100,000 years to get across, from one end to the other.
How are we the only people in space?
We don't know that we are. There could easily be other civilizations - thousands or millions of them - in our galaxy or in others, but space is so immensely huge that we might not EVER know about it.Imagine a beach. Imagine that each grain of sand on the beach is a solar system. We've explored (imperfectly) our single grain of sand. There are billions of stars in THIS galaxy, and billions of other galaxies beyond.
Why doesn't the sun burn out?
The sun doesn't burn out because it undergoes a constant process called nuclear fusion where hydrogen atoms are converted into helium, releasing huge amounts of energy. This process generates enough heat and pressure to counteract the gravitational force trying to collapse the sun, maintaining its stability. The sun has been sustaining this balance for billions of years and is expected to continue doing so for billions more.
Does Tokyo have a public transportatin system?
Tokyo has a huge subway system.
How can the amazon rain forest help the ecosystems of entire planet?
