There are several ways, the most popular are:
1) Just like a star affects the motion of a planet so does the planet affect the motion of the star, but only in small degree. Astronomers look at stars and see if they have a periodic shift in their movement and conclude that a planet is causing it.
2) If the orbit of a planet is "edge on", then it will eclipse the star and cause a periodic reduction of its light by up to 2%.
Yes, other gems can be found near quartz deposits, especially in areas with high mineralization. Some common gems found near quartz deposits include amethyst, citrine, and various types of agates. Gem hunters often search near quartz veins to find a variety of gemstones.
The region beyond Earth's atmosphere is known as outer space or simply space. This area is vast and contains stars, planets, comets, asteroids, and other celestial bodies. It is a near-vacuum environment with little to no atmosphere.
Subduction zones are found near convergent plate boundaries, where two tectonic plates collide and one plate is forced beneath the other, leading to the formation of deep ocean trenches and volcanic arcs.
There are numerous characteristics that the Earth has but other planets do not. Some of them areLife: The most important characteristic that the Earth possesses and other planets do not is "life". So far, its the only planet discovered by mankind to have life. Although some ufologists (people who study about life in other planets) claim that life is present in other parts of the universe, these are only hypothetical views.Liquid Water: Liquid water till yet has been discovered only on Earth and no other planet. Although certain planets like Mars has polar zones covered with ice, yet the probability of liquid water is very less. The ice actually has never melted for years.Atmospheric Composition: The atmospheric composition and atmospheric pressure is a major point to be noted here. The atmospheric composition of Earth with 79% Nitrogen, 21% Oxygen and very little carbon dioxide (0.04%) is just the perfect ratio for sustainance of life. Planets like Jupiter has most of the atmosphere composed of methane, hydrogen and ammonia. Other bodies like the Moon (not a planet) has no atmosphere at all because of low gravity.There are other factors like gravity, size, colour (the Earth appears blue from space), etc are also there which differentiate it from other planets.
Pumice is commonly found near volcanic areas or where there has been past volcanic activity. It can be found in regions with active volcanoes, volcanic islands, or near volcanic ash deposits.
near other stars or in empty space
Some planets seem brighter - not all of them. Planets are quite near to us, as compared to the stars.
Because the stars are relatively so far away, all planets of this solar system have the same number of stars near them.
Stars near the Moon are not planets. Planets in our solar system, such as Venus, Mars, and Jupiter, are sometimes visible near the Moon depending on their position in their orbits, but they are not stars. Stars are celestial objects that generate their own light through nuclear fusion, while planets do not emit light but instead reflect light from the Sun.
Within our solar system at the present time, no. Regarding planets orbiting other stars outside our solar system, our present technology is nowhere near able to tell.
Virtually all of the known planets are near a star. Occasionally, a rougue free floating one will be sighted, but they are rare anomalies.
no, as there is no gas to make noise.
There is not much solid information known about planets in other galaxies. Most planets discovered so far are in our own galaxy. This is because it is easier to discover a relatively near-by planet than one that is much farther away. However, the planets found so far make it likely that in our own Milky Way, and therefore other galaxies as well, have at least as many planets as stars.
There are no known planets located near the star Algol, which is a binary star system consisting of two stars. The distance between the two stars is relatively close, making it difficult for planets to stably orbit either of the stars.
We only know about the number of moons for our own solar system. Technology now lets us see very large planets around other nearby stars. We have found a few near Earth size. However currently we can not detect moons around planets in other solar systems.
Two stars orbiting each other are "binary stars" ...a group of stars near each other, may be formally or informally known as a "cluster".
The planets constantly move through the constellations and other patterns of stars, always staying pretty close to the same track. Sadly, their track never comes anywhere very close to Orion.
