You can see several planets from Earth at night, depending on their position in the sky and the time of year. Here are the most common ones:

* Mercury: Difficult to spot due to its proximity to the sun, but sometimes visible low on the horizon just after sunset or before sunrise.

* Venus: Often the brightest object in the night sky, appearing as a very bright "star."

* Mars: Can be seen as a reddish "star" when it's in a favorable position.

* Jupiter: A bright, white "star" with noticeable size.

* Saturn: A fainter, yellowish "star" with rings (though the rings are difficult to see without a telescope).

Note: It's best to use a stargazing app or website to see when and where specific planets will be visible in your location.
