How many rings does Mercury have?

Unlike Saturn, Mercury does not have any rings or moons. It is the closest planet to the sun, and daytime temperatures can peak around 800 degrees Fahrenheit.

Without a moon or rings, Mercury is a fairly plain planet to observe. It is a terrestrial planet, which means it has solid, rocky surface. Mercury is the smallest of all the planets in the solar system and is only slightly larger than Earth's moon. Because of Mercury's close proximity to the Sun, it only takes 88 Earth days to make a complete orbit, and due to its slow rotational speed, a normal day on Mercury lasts for 59 days.
