solar system
Hundreds of billions of stars, some of them with planets.
yes
Extrasolar planets are planets found orbiting stars other then our own.
Galaxies are formed by stars, planets, comets, meteors, and other space bodies.Stars have their own source of energy, tones of hydrogen burned into hellyum every second, while planets don't have, and get heat from the nearest star. Stars are the furnace of the universe eventually allowing planets to develop life, like the Earth.
Orbiting stars. We know of eight planets orbiting our Sun, and we know of over 300 planets orbiting other stars.
there are more planets than stars because to every star there could have several planets
A person who studies planets and galaxies is called an astronomer. Astronomers observe and analyze celestial bodies such as planets, stars, and galaxies to understand their composition, behavior, and evolution. They use telescopes and other instruments to gather data and make scientific discoveries about the universe.
we are in the milky way galaxy
Most extrasolar planets are found close to their parent stars because current planet detection methods are biased towards detecting larger planets that are closer to their stars due to the limitations of technology. These close-in planets are easier to detect because they have a greater impact on their star's light or motion. As technology and detection methods improve, we are discovering more distant planets from their stars.
No. Other stars have been found to have planets orbiting them.
Planets orbit stars.
The center of the elliptical galaxy is very dense with many stars, and density decreases farther out.
