2 days ago · Mercury is the first planet from the Sun and the smallest in the Solar System. In English, it is named after the ancient Roman god Mercurius , god of commerce and communication, and the messenger of the gods. Mercury is classified as a terrestrial planet, with roughly the same surface gravity as Mars.
Jun 3, 2024 · Mercury, the innermost planet of the solar system and the eighth in size and mass. Its closeness to the Sun and its smallness make it the most elusive of the planets visible to the unaided eye. Because its rising or setting is always within about two hours of the Sun’s, it is never observable when the sky is fully dark.

Mercury is the smallest and innermost planet in the Solar System, located 0.39 astronomical units from the Sun. It has a diameter of 4,880 kilometers and a mass of 3.3 x 10^23 kilograms, making it only slightly larger than Earth's moon.
Jun 3, 2024 · Mercury is an extreme planet in several respects. Because of its nearness to the Sun —its average orbital distance is 58 million km (36 million miles)—it has the shortest year (a revolution period of 88 days) and receives the most intense solar radiation of all the planets.

Jun 17, 2024 · Mercury is the closest planet to the Sun in our solar system and the smallest of the eight major planets. It has a diameter of about 4,880 kilometers, making it only slightly larger than our Moon. Due to its small mass, its surface gravity is only 38% of Earth's gravity.
5 days ago · Mercury is the smallest planet in the Solar System in both mass and diameter. It’s 18 times less massive than the Earth, and its diameter barely reaches two-fifths of the Earth’s size. To give you a better understanding of Mercury’s size, let’s say that it’s only a third larger than the Moon.
