From the surface of Mars, Earth is visible as a bright star-like object in the night sky. The visibility of Earth from Mars varies depending on the positions of the two planets in their respective orbits around the Sun.
When Mars and Earth are aligned closely (a configuration known as opposition), Earth can be quite bright and may even be visible to the naked eye. At its closest approach, Earth can be about 54.6 million kilometers (33.9 million miles) away from Mars. However, when the two planets are on opposite sides of the Sun, the distance increases significantly, making Earth appear fainter and more distant.
In terms of appearance, Earth is not visible as a disc like the Moon appears from Earth; instead, it looks like a bright "star" to an observer on Mars. Alongside Earth, one might also observe other celestial bodies, including the Moon, if conditions are suitable.
In summary, Earth is visible from Mars as a bright point of light, with its visibility varying based on the planets' relative positions.
