Stars are intrinsically brighter than planets, typically. Planets (in general) shine by reflected starlight, whereas stars produce their own light. The exception are black dwarfs, which are burned out stars, and neutron stars which do not emit much light in the visible spectrum.
Some planets glow a bit in the infrared from their own internal heat as well.
As seen from earth Venus outshines any star, and Jupiter rivals Sirius, Arcturus, and Vega in brightness. These stars are all brighter than Mars and Saturn. The reason the planets appear brighter than some stars is because they are very close, while the stars are very, very far away.

Why do planets appear brighter than stars?
Because they're very close to the sun and thus reflect a lot of the sunlight. It also helps that they are very close to us in terms of the other stars in the sky.
Are stars really little moons?
No. Stars are much larger than planets or moons. Stars are suns, some larger and brighter than our own.
How can stars have different absolute brightness?
Big stars are brighter than small stars, and hot stars are brighter than cool ones.
Why do planets look brighter than stars?
They are a lot closer than the stars. The nearest star, Alpha Proxima is 4 light years away. The planets are at most a few light hours away. Although they don't emit light, several of them have cloudy or sandy surfaces, making them highly reflective of sunlight. somtimes stars are brighter like the sun thats a star
Is the sun brighter because it is closer than the other stars?
It is better to say that the sun appears brighter because it is closer. Some stars are actually brighter than the sun.
Why do planets seem brighter than stars?
Some planets seem brighter - not all of them. Planets are quite near to us, as compared to the stars.

When compared with most stars are planets brighter or smaller?
Well,planets do not have any light of their own so they are definitely not brighter and yes there may be some stars smaller than the planets but most of the stars are bigger than the planets . But on the whole the Space is not that much explored so that we can get any cumulative answer.

How can an observer from earth distinguish planets from stars?
-- The planets you can see with your naked eye are generally brighter than a typical star. -- They also twinkle less than the stars do. -- Planets appear as small disks even in binoculars or small telescopes, but stars never do. -- From one night to the next, or certainly from one week to the next, the patterns formed by stars don't change, but planets move through those patterns.
Are brighter than stars.?
Quasars A+
Why do some dwarf stars appear brighter than giant stars?
Because they are closer or actually brighter.
Are stars bigger than moons?
Yes, much bigger. The stars appear tiny because they are unimaginably far away. The stars we see at night are suns, some bigger and brighter than out son, some with their own planets orbiting them.
