A star can appear to become brighter and dimmer on a regular basis if it is a variable star. Variable stars can pulsate, eclipse with another star, or vary in brightness due to other factors. By observing these fluctuations in brightness over time, astronomers can gain insights into the star's properties and behavior.

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.
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.
Are stars cooler than the sun brighter or dimmer?
Stars can be both cooler and brighter or hotter and dimmer than the Sun, depending on their size and age. Generally, larger and younger stars are hotter and brighter than the Sun, while smaller and older stars can be cooler and dimmer.
What brightness color of star?
The brightness and color of a star are related to its temperature and size. Hotter stars appear blue or white and are brighter, while cooler stars appear red or orange and are dimmer. The brightness of a star can also vary based on its distance from Earth.
When mars is in retrograde motion will it appear brighter or dimmer?
When Mars is in retrograde motion, it does not affect its brightness. Mars will continue to appear at its usual brightness in the night sky regardless of its retrograde motion. Retrograde motion refers to how the planet appears to move in the sky, not its actual brightness.

WHAT HAPPENS As a celestial object moves farther away from the viewer it will appear .?
brighter btw add me on fb @kevin garcia
How do colors relate to filming sets?
Films use colors... The colors are dimmer because when the light shines through it will appear brighter.

Regular Dimmer will work.
Is Rigel brighter or dimmer?
Rigel is one of the brightest stars in the sky.
What happen to the shadow if the light get dimmer?
If the light gets dimmer, the shadow will become less defined and appear lighter. As the light source decreases in intensity, the shadow cast by the object will become less sharp and more diffused.
What is dimmer switch?
Usually a switch will only let you choose between ON and OFF, but a dimmer switch will let you change between Brighter or Darker.
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.
