We are all made of stardust
I don't think so. From Wikipedia (article on brain): "The cerebral cortex of the human brain contains roughly 15-33 billion neurons, perhaps more, depending on gender and age,..." The galaxy has an estimated 200 billion stars.
This represents a galaxy, which is a massive collection of stars, gas, dust, and other celestial objects bound together by gravity. The Milky Way is an example of a galaxy that contains millions of stars, along with interstellar gas and dust.
Not in the galaxy- It is fairly ordinary in size compared to other stars. However, it is, of course, the largest body in the solar system- it takes up about 99% of the matter.
Names have been assigned to celestial bodies by astronomers and others. That does not mean that every celestial body has been given its own name. The Sun is what we call the body that Earth revolves around. That name is not usually gtiven to any other celestial body.
the most common thing on earth crust as well as in human body is water .
Large collections of gases accumulate to form a heavy gas body. This body is so hot that the temperature is high enough to initiate and sustain nuclear fusion. That's how stars are born.
Yes, the Sun is a fixed star in the sense that it is a stable, self-luminous celestial body located at the center of our solar system. It is one of countless stars that make up the Milky Way galaxy and does not move in relation to other stars in our galaxy over short timescales.
Jupiter and stars are both spherical (ball-shaped) and they both orbit a larger body of some sort. Jupiter orbits our Sun, and stars orbit the center of their galaxy, and sometimes stars orbit another close star.
A nerve is a bundle of individual neurons. There are approximately 100 billion neurons in the human body (about the same number of stars in our Milky Way galaxy), but there are only 214 nerves in the human body.
No, constellations are patterns of stars that we see from Earth. The moon is a celestial body that orbits Earth, so it does not have its own constellations.
The Universe is the largest body in the...well, the Universe. It never stops expanding. The Universe is full of billions of galaxies, which range in shape and size. However, none are even close to being compared in size to the Universe.
They seem to move as the earth turns. Their apparent motion is illusory. They DO actually move, however, but they are so far away that their motion can only be determined over long time periods with very precise instruments. Keep in mind, however, that all stars are actually moving: stars move around in response to the gravity of other stars and material within and around the galaxy. All the stars are rotating around the center of the galaxy and the galaxy itself is moving in relation to other galaxies. However, almost none of this motion is fast enough over the scale of distance involved for us to notice it within our lifetimes.
