The largest known Near-Earth asteroid is 1036 Ganymed with a diameter of nearly 41 kilometers (25.5 miles). Scientists are working to identify Near-Earth asteroids with diameters of 1 kilometer (0.6 mile) or more that may pose a danger of colliding with the Earth.

What is the brightest asteroid seen from Earth?

Vesta is the brightest asteroid visible from Earth. It is regularly as bright as magnitude 5.1, at which times it is faintly visible to the naked eye. Its maximum distance from the Sun is slightly greater than the minimum distance of Ceres from the Sun, though its orbit lies entirely within that of Ceres.

What are the 3 largest asteroids?

Ceres, Pallas, and Vesta are the three largest asteroids. Even though they are much smaller than the planets (Ceres, the largest asteroid, has only 1% the mass of the Moon), they are still capable of causing changes in the orbits of Mars and the Earth.
