It used to make a huge difference. When telescopes were poor and space flight was unheard of. Nowadays the telescopes such as Hubble and Spitzer Infrared mean the we can see exactly how big, bright, and colourful a star is. So to answer the question: To the naked eye, yes. But with a descent telescope, absolutely not.
What else can I help you with?
What is a stars brightness known as?
A star's brightness is known as its magnitude. Stars with lower magnitude numbers are brighter than stars with a higher magnitude number.
What magnitude is the big dipper?
The Big Dipper is not a star, but an asterism made up of seven bright stars that are part of the constellation Ursa Major. The stars in the Big Dipper range in magnitude from about 1.8 to 3.3.
Is magnitude and and apprent magnitude the same thing?
apparent magnitude is how bright a stars seems from earth. magnitude (i think called actual magnitude [I cant remember]) is how bright a star ACTUALLY is.Have a nice day.
Are the brightest stars low or high magnitude?
The brightest stars have a low magnitude. Magnitude is measured on a logarithmic scale where lower numbers indicate brighter objects. The brightest star in the night sky, Sirius, has a magnitude of -1.46.
What is a second magnitude star?
A second magnitude star is a star that is relatively bright in the night sky, typically with an apparent visual magnitude between 1.5 and 2.5. These stars are easily visible to the naked eye and are brighter than third magnitude stars but dimmer than first magnitude stars.
Explain why size is the only factor that determines the stars absolute magnitude?
The absolute magnitude is a measure of the star's luminosity hence the smaller the size the less the absolute magnitude.
What the relationship between magnitude and size of the star?
The brightness of a star depends on its temperature, size and distance from the earth. The measure of a star's brightness is called its magnitude. Bright stars are first magnitude stars. Second magnitude stars are dimmer. The larger the magnitude number, the dimmer is the star.The magnitude of stars may be apparent or absolute.
Is the size of a star the only factor that determines the stars absolute magnitude?
yes yes it does
What is magnatued?
It appears there may have been a misspelling. If you meant "magnitude," it refers to the size or importance of something. Magnitude can be measured in various ways depending on the context, such as in physics (magnitude of force), astronomy (magnitude of stars), or seismology (magnitude of earthquakes).
How big are the stars that you can see from the earth?
The stars visible from earth (except the sun) represent stars from the size of our sun to supergiants. How "big" they look to us is as much or more a function of their distance from us as it is their size. With good vision, on a clear night, the faintest stars we can see are about fifth magnitude. With a 70 mm telescope, that jumps to about 9th magnitude.
What is a stars brightness known as?
A star's brightness is known as its magnitude. Stars with lower magnitude numbers are brighter than stars with a higher magnitude number.
How big is 6.6 magnitude?
In the context of stars, a magnitude is not a measure of size but of brightness or apparent brightness. The apparent magnitude of the sun is -27 while Sirius, the brightest star has a magnitude of only -1.4: negative magnitudes are more bright, and stars with magnitudes greater than 6.5 are not visible to the naked eye. However, the sun is a star of modest modest size compared with some of the giants and supergiants.
Will an earthquake get bigger if it is deeper?
No. Size does not necessarily affect the magnitude of an earthquake. In fact, a deep earthquake will have less of an effect on the surface than a shallow earthquake of the same magnitude.
Why is the absolute magnitude of some stars greatar than their apparent magnitude?
The question is: Why is the apparent magnitude of some stars less than their absolute magnitude. Or: Why do some stars not look as bright as they really are ? The answer is: Because they're so far away from us.
What does a magnitude mean?
There are two main meanings of magnitude. One is the absolute value. In this context, the magnitude of the number is its size, irrespective of the sign. So, the magnitude of -4 is the same as the magnitude of 4. The other is in the sense of the order of magnitude. This is usually used when the measurement scale is logarithmic. The apparent brightness of stars, for example is expressed in magnitude. Brightest stars = magnitude 1. Stars half as bright = mag 2, quarter as bright = mag 3 etc. Or [deci]bel for the loudness of sound. Incidentally, the Richter scale, for measuring the strength of earthquakes is not a systematic measure in this sense. The measure is largely based on the effects of the quake at the surface.
A measure of a stars brightness is called its?
Magnitude. First magnitude descibes many bright stars, and a span of five magnitudes represents a difference of a hundred times in the star's brightness. The dimmest stars seen by a perfect human eye in perfect conditions is 6th magnitude.
What magnitude of star can the human eye see?
The human eye can typically see stars with a magnitude of about +6 or brighter on the magnitude scale. Brighter magnitudes correspond to dimmer stars.
