When viewed from earth a red star and a blue star can appear to be equally bright what can you infer about these two stars?
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.

Why does venus appear to be very bright from earth?
Earth's nearest neightbor
Viewed from Pluto would the Sun would appear more than a thousand times fainter than on earth?
Yes, from Pluto, the Sun would appear more than a thousand times fainter than on Earth due to the increased distance. Pluto is an average distance of about 3.7 billion miles away from the Sun, leading to a significant decrease in sunlight intensity compared to Earth's distance of about 93 million miles.
When do solar eclipse appear?
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.
How big would the sun appear from Venus?
The Sun would appear about 1/3 smaller from Venus compared to how it appears from Earth. This is because Venus is closer to the Sun than Earth, so its diameter is larger in the sky when viewed from Venus.
Is it true that two stars that have the same brightness are the same distance from earth?
Not necessarily. Two stars can have the same brightness but be at different distances from Earth. The distance of a star affects how bright it appears to us, so a closer dim star may appear as bright as a farther bright star.
Why does venus appear to be very bright from earth?
Earth's nearest neightbor
A bright star can appear dimmer than a less bright star if the bright star is?
If the bright star is located farther away from Earth than the less bright star, it will appear dimmer due to the inverse square law of light intensity. The amount of light reaching Earth decreases with distance, so a closer, less bright star can appear brighter than a further, brighter star.
How bright does a star appear from earth?
It depends on its intrinsic brilliance and its distance from the observer
What planets appear fifty degrees from the sun as viewed from earth?
All planets except Mercury can appear 50 degrees from the Sun.
What are the two factors that determine how bright a star looks from earth?
The two factors that determine how bright a star looks from Earth are its intrinsic brightness, or luminosity, and its distance from Earth. Stars that are more luminous will appear brighter, while stars that are closer to Earth will also appear brighter.
Which planet is second only to the moon in brilliance in the night sky?
Venus is the planet that is second only to the moon in brilliance in the night sky. Its close proximity to Earth and its thick cloud cover reflect a significant amount of sunlight, making it appear very bright in the sky.
How could the Sun appear at different angles when viewed at the same time from different locations on Earth?
the sun does not move but the earth does spin around
Why The Moon and the planets appear bright at night?
The Moon appears bright at night because it reflects sunlight. Planets appear bright due to the reflection of sunlight off their surfaces, as well as their own internal heat that emits light. Additionally, planets are much closer to Earth than stars, making them appear brighter in the night sky.
When viewed from above rainbows are what shape?
Rainbows are an optical illusion, they are not "real". You cannot view them from above; they will always appear the way they appear from the ground.
Why is space station so bright?
Space stations can appear bright in the night sky because they reflect sunlight off their solar panels and metal surfaces. This reflection can make them appear as bright, moving objects as they orbit the Earth.
How would they apear If Deneb and Rigel were located at Alpha Centuari's distaance from earth?
they would appear bright enough to be seen, although too bright to look at
Viewed from Pluto would the Sun would appear more than a thousand times fainter than on earth?
Yes, from Pluto, the Sun would appear more than a thousand times fainter than on Earth due to the increased distance. Pluto is an average distance of about 3.7 billion miles away from the Sun, leading to a significant decrease in sunlight intensity compared to Earth's distance of about 93 million miles.
