No. The Sun is
We would say that the moon is the secondbrightest, after the sun.
The Moon is illuminated by the Sun. At full moon, we see the bright part - the illuminated part. At new moon, we see mostly the dark part. (This part is also slightly visible, due to light reflected from the Earth.)
brightest
No, Jupiter is typically the 4th brightest object in the sky after the Sun, Moon, and Venus. It can vary in brightness depending on its position in its orbit and its alignment with Earth.
venus
Assuming you mean in the Earth's night sky, Venus is the next brightest natural object seen from Earth.
Blue-white stars are the hottest and brightest stars; Sirius A (and its white dwarf companion Sirius B) is the brightest star in Earth's night sky.
Venus
The moon is the closest heavenly body to the earth and because of its relatively high albedo it reflects a lot of the light falling on it hence it is the brightest object in the night sky. Similar reasons also apply to Venus, which is also a very bright object.
The sun and the moon are not planets. The sun is a star and the moon is a natural satellite. The brightest planet in Earth's sky is Venus.
Quite often, that would be the clouds. If you mean objects outside of Earth's atmosphere, the answer is the Moon.
becauce it is the brightest and beautifull..........
