How is the sun different from other stars relative to earth?
The Sun is bigger than some stars and smaller than others. It is brighter than some stars and dimmer than others. Relative to the Earth it is much closer than all other stars.
What causes some stars to be brighter than others?
In absolute terms larger (more massive) stars shine more brightly than less massive ones. In relative terms (as seen from Earth) more distant stars appear dimmer than closer ones.
What are some of the general terms used to describe star sizes?
Stars can be classified by temperature, pressure, age, size or colour. Star classification according to size is found out using temperature and pressure classifications. The temperature tells them the surface brightness of a star, and the pressure tells them an approximate size of the star, which tells them whether the star is a giant, a dwarf or something in between. These two measurements taken together can often give information on the star's age and distance from the earth.
Can stars be dark?
Stars emit light due to thermonuclear reactions happening in their cores. Therefore, by definition, stars are luminous and cannot be dark. However, some stars may appear dimmer to us based on their distance, size, or phase in their life cycle.
Why are some of the stars very faint?
Some stars appear faint because they are located far away from Earth, making them difficult to see with the naked eye. Others may be faint due to their size and temperature, emitting less light compared to brighter stars. Dust and gas clouds in space can also block or dim the light from stars, making them appear fainter.
How is the sun different from other stars relative to earth?
The Sun is bigger than some stars and smaller than others. It is brighter than some stars and dimmer than others. Relative to the Earth it is much closer than all other stars.
Are stars similar to the size of earth?
Some stars are bigger than the planet like the sun but some are small. The size varies.
How does the size of the sun compare to the stars?
The sun is bigger than some stars, but it is smaller than some stars too. The sun is the brightest star that is closest to earth, causing it to be seen daily.
How many stars does the constellation Cygnus has?
There are 9 major stars in Cygnus. There are 6-9 stars, depending on which map you look on. Some earlier maps show 6 stars, but some other maps show 9 stars.
Are the stars you see smaller than the sun?
Some stars are smaller than the sun, some are smaller, and some are about the same size. The sun is a star that is larger than average, but not out of the ordinary.
Who is big sun or stars?
Some stars are larger than our sun while some are not.
How do the spectra of some stars shift?
There is a Doppler shift which results from the relative motion of the star in question, either toward or away from us as we observe it.
Since the stars appear to be some source of magic and God created them would that show magic comes from God?
No. The stars are not a source of magic.
What are the constallations?
In astronomy, a constellation is a specific group of stars which has been given a name. In astrology, the relative position of stars or group of stars that are said to influence people or events. In general, a group of things, ideas, events, or characteristics that are related in some way.
What are the size of the stars?
For example, our Sun has a diameter of about 1.4 million kilometers. Some other stars are bigger - up to hundreds of times bigger. The majority of stars, however, are smaller than our Sun.
What causes some stars to be brighter than others?
In absolute terms larger (more massive) stars shine more brightly than less massive ones. In relative terms (as seen from Earth) more distant stars appear dimmer than closer ones.
What are some examples of animals that are small but strong?
Some examples of small but strong animals include ants, dung beetles, and hummingbirds. These animals may be small in size, but they possess impressive strength relative to their body size.
