In the case of an occulting binary star system. You have two stars that orbit each other. When one star passes between the other star and the observer it blocks (or occults) the farther one thus decreasing the amount of light to the observer by the brilliance of the farther star. This only happen if both stars and the observer are so aligned to end up on the same straight line at some point.
Quite simply; some stars are larger than others, often many thousands of times. Also, the stars you see in the night sky are at varying distances from the Earth. Some are as close as 4.5 light years away and others are many thousands of light years away.
1). Some stars are brighter or dimmer than others.
2). Some stars are nearer or farther from earth than others.
So any given star can be bright and near, bright and far, dim and near, or dim and far.
It's kind of like the reason why some instruments in the band sound louder than others.
A piccolo has to be a lot nearer to you in order to sound as loud as a far-away Trumpet.
You can't tell from the information given in the question.
We know that a star appears dimmer and dimmer as it gets farther away. But we don't know
whether Star-A is far enough away to compensate for being brighter than Star-B.
In order to answer the question, we have to know
==> by how much is Star-A brighter than Star-B, and
==> how much farther away is it than Star-B ?
Then we're in a position to do some calculating.
Identical stars could have a different brightness if they have different distances from us.
The brighter star is closer. Astronomers use this idea to calculate how far away distant objects are.
That means the star that is further away also has a larger absolute (real) brightness.
because it's closer to earth.
Star B is closer.
Earth's nearest neightbor
Yes, it is true. The Sun would appear more than a thousand times fainter viewed from Pluto than it would as viewed from Earth.
They would both be bright enough to be seen by, and probably too bright to look at
A solar eclipse occurs when the moon passes between the Sun and the earth. The moon covers most of the sun as viewed from earth. Solar eclipse can only appear when the there is a new moon.
The amount of starlight received on Earth is called apparent magnitude. This is the measurement of how bright the stars appear from Earth.
Earth's nearest neightbor
Yes, it is true. The Sun would appear more than a thousand times fainter viewed from Pluto than it would as viewed from Earth.
It depends on its intrinsic brilliance and its distance from the observer
All planets except Mercury can appear 50 degrees from the Sun.
From the vicinity of Jupiter, it would appear much smaller than from Earth, and about 1/27th as bright, like an extremely bright star.
the sun does not move but the earth does spin around
Brighter, since Mars is closest to Earth in its orbit and in a full phase as viewed from Earth.
they would appear bright enough to be seen, although too bright to look at
They would both be bright enough to be seen by, and probably too bright to look at
The "apparent" reverse or backwards motion of a planet as observed from Earth. The innermost planets appear to have a retrograde motion when viewed from Earth.
A solar eclipse occurs when the moon passes between the Sun and the earth. The moon covers most of the sun as viewed from earth. Solar eclipse can only appear when the there is a new moon.
The color of the sky on earth would still appear blue but the "sky" around you would be black
