Dwarfs are bright because they are galaxies which have their own stars. They are not closer to the earth than the sun.
The Earth is much smaller than the sun. The sun is about 109 times larger in diameter than Earth. This size difference allows the sun to maintain its powerful gravitational force over the planets in the solar system, including Earth.
The compound is called calcium chloride. It is composed of Ca2+ cations and Cl– anions; those ions are stable since they have filled valence shells. Its ionic formula is written as CaCl2, the neutral combination of these ions.
The sun's radiation heat to the surface of the entire Earth is approximately 2,500 times greater than the heat coming from the Earth's interior. This is due to the immense energy output of the sun compared to the relatively smaller amount of heat generated within the Earth.
No, the Sun is older than the Earth.
A bright cloud in a dark sky often occurs during sunrise or sunset when the angle of the sun casts light onto the cloud from below the horizon, creating a contrast between the cloud and the dark sky. This phenomenon can also happen when the cloud is filled with ice crystals that reflect sunlight, making it appear bright even in dark conditions on the ground.
A red dwarf star is less bright than the sun. Red dwarfs are small, cool stars that emit energy at a much lower rate compared to the sun. Despite being less luminous, red dwarfs are the most common type of star in the universe.
Because luminosity is a measure of brightness over distance. Also white dwarfs are a hundred times smaller than the Sun. Most white dwarfs are a long way away and thus are difficult to see.
There are other "main sequence" stars smaller than the Sun, but the classes of much smaller stars are:white dwarf stars (once Sun-like but no longer support fusion)red dwarfs and orange dwarfs (small dim stars that have very long lives)"brown dwarfs" (oversized Jovian gas giants with little or no fusion)neutron stars (smaller than the Earth but immensely dense, remnants of massive stars that went supernova)
Stars known as red dwarfs are smaller and cooler than the Sun. These stars have masses less than half that of the Sun and can be significantly dimmer. Red dwarfs are the most common type of star in the universe.
Some white dwarfs are older than the sun, and some are not. More massive red dwarfs form from stars larger than the sun, which do not last as long.
The sun would look much smaller than it does from Earth but still bright.
There are two types of star that can be red. Red dwarfs are smaller than the sun. Red giants are far larger than the sun.
Our sun is about average compared to other stars. Some are much smaller (white dwarfs) and others are much larger.
The majority of stars in our galaxy are red dwarfs, which are smaller and cooler than our sun. They make up about 70-80% of the stars in the Milky Way.
A white dwarf is much denser than the Sun. White dwarfs have a typical density around 1 million times greater than the density of the Sun, resulting in a mass similar to the Sun's but packed into a much smaller volume.
yes the sun is the biggest out of all planets however the sun is a star.
Well, let me tell you, it's truly fascinating! White dwarfs are actually much smaller and cooler than supergiants, so they seem dimmer to our eyes. But despite their dimness, aren't they still shimmering orbs of beauty in the vast cosmos? Just remember, every star has its own brilliance and charm.
