Asteroid Vesta is one of the largest objects in the asteroid belt located between the orbits of Mars and Jupiter. It was discovered on March 29, 1807, by the German astronomer Heinrich Wilhelm Olbers and was named after the Roman goddess of the hearth and family.
Vesta has a diameter of about 525 kilometers, which makes it the second-largest asteroid in the belt after Ceres. Its mass is about 9% of the total mass of all objects in the asteroid belt. The asteroid has a nearly spherical shape, which indicates its differentiated structure: Vesta has a crust, a mantle, and a metallic core, which makes it similar to the terrestrial planets.
The surface of the asteroid is rich in geological structures: numerous craters, mountains, valleys, and areas with different albedo (reflectivity). One of the most notable features is the giant crater Rhea Sylvia at the south pole, left by a massive impact. Studies also suggest the presence of water ice beneath Vesta's surface, although its surface is largely dry.
In 2011, NASA launched the Dawn mission to study Vesta and the dwarf planet Ceres. Dawn reached Vesta in July 2011 and spent about a year collecting data on its topography, composition, and interior structure. Studies have shown that Vesta is the source of some meteorites found on Earth (the HED group of meteorites), making it an important target for studying the formation and evolution of the planets in the Solar System.
Vesta's unique nature as a protoplanet and its relatively well-studied surface continue to attract the attention of scientists and amateur astronomers, making it one of the most intriguing research targets in the asteroid belt.
