What is the main reason that Venus would appear brighter at point Q rather than at point R as seen from the Earth?
The main reason Venus would appear brighter at point Q rather than R is due to the angle of illumination. At point Q, Venus is closer to the Sun, so it is receiving more direct sunlight, making it appear brighter. At point R, Venus is farther from the Sun and receiving less direct sunlight, resulting in a dimmer appearance.

Which is brighter mars or Saturn?
Saturn is brighter than Mars in our night sky. Saturn's rings reflect more sunlight, making it appear brighter from Earth. Mars is usually visible to the naked eye and has a reddish color, while Saturn has a yellowish tint.
Why is Jupiter in the night sky brighter than betelgeuse?
Jupiter is brighter than Betelgeuse in the night sky because it is much closer to the Earth in comparison to Betelgeuse(Betelgeuse is more than 500 lightyears away form the Earth). This way, Jupiter appears larger than Betelgeuse, and celestial objects that appear larger also appear brighter than objects that appear small.
Why does a medium-siza star appear brighter than the others?
A medium-sized star may appear brighter than other stars due to its luminosity, which is a measure of the total amount of energy it emits per unit time. This brightness is determined by factors such as the star's size, temperature, and distance from Earth. In general, larger and hotter stars tend to be more luminous and thus appear brighter in the night sky.
What is meant by the saying the earth is tilted?
Rather than being perpendicular to the orbital plane of the Earth around the sun, the rotational axis of the Earth is tilted. This is the reason we have seasons.
Why is it easiest to see mars when it is closer to earth?
Because it will appear larger, and it will thus (and also because its closer) appear brighter. Remember that the intensity of light perceived is proportional to the surface area of the emitter, and inversely proportional to the square of the distance to the emitter.
What are Two reasons why one star would be brighter than another?
One reason could be that the brighter star is larger and hotter, emitting more light. Another reason could be that the brighter star is located closer to Earth, making it appear brighter in the sky.
Is a star brighter if it is closer to earth?
Yes, a star appears brighter if it is closer to Earth because the brightness of a star we see is affected by its distance. The closer a star is, the greater the amount of light that reaches Earth, making it appear brighter in the sky.
Why would one red giant appear brighter than the other?
Three possibilities: It is brighter (some are brighter than others), it is bigger, or it is closer to earth.
Why are some stars brighter than others?
Stars appear brighter depending on their size, temperature, and distance from Earth. Larger and hotter stars emit more light, making them appear brighter. Additionally, stars that are closer to Earth will appear brighter than those that are farther away.
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.
Is it true that the closer a star is to earth the brighter it appear?
That is one factor. The size of the star is the other.
Why are stars brighter when thay are seen from the moon?
Stars appear brighter when seen from the Moon because there is no atmosphere on the Moon to scatter or absorb light. This allows starlight to pass through to our eyes without interference, making them appear brighter compared to when seen from Earth.
Why do stars appear brighter or dimmer?
Stars appear brighter or dimmer depending on their distance from Earth. The closer a star is, the brighter it appears, while stars that are farther away appear dimmer. Additionally, stars can also vary in brightness due to changes in their own luminosity or if they are being obscured by interstellar dust or gas.
Why does Sirius appear brighter than Pollux in your nightime sky?
Because Sirius is closer to the earth that's why it is bigger

The sun looks larger and brighter because it is what star to the earth?
The sun is the closest star to Earth, which is why it appears larger and brighter in our sky compared to other stars. Its proximity allows for more direct sunlight to reach us, making it appear more prominent.
