What is the brightness of the planet mercury?

Answer 1

Approximately -2.6 to 5.7, "apparent magnitude".

Mercury's brightness varies as it orbits the Sun.

Mercury is difficult to see because it's so close to the Sun in the sky.

So, its apparent magnitude is a bit misleading as a guide to ease of observation.

(Also, remember that it is dangerous to look directly at the Sun.

Astronomers have developed safe methods for observing things close to the Sun.)

Answer 2

The brightness of the planet Mercury varies depending on its position relative to the Sun and Earth. At its brightest, Mercury can reach a magnitude of around -2.5, making it one of the brightest objects in the night sky. However, its proximity to the Sun means that it is often difficult to observe due to its low position in the sky and being easily drowned out by the Sun's glare.
