No. The sun is very close to us so it seems very bright. There are a lot of stars that are much brighter than it, but are very far away. It is the same with the other stars. There are some very bright ones that are very far away and some dimmer ones that are closer to us. After the sun, the next brightest star is Proxima Centauri. The brightest star in the night sky that we see is Sirius, which is close, but much further away than Proxima Centauri.


What is the brightest visible planet in our sky at night?

The brightest visible planet in our night sky is Venus, often referred to as the "Evening Star" or "Morning Star" due to its bright appearance at dawn or dusk. It shines brightly because of its thick, reflective cloud cover and its proximity to Earth. Other planets like Jupiter can also appear very bright, but Venus typically outshines them. Its brightness and visibility make it a prominent feature in the night sky.
