It's an asteroid and only an asteroid.
A big one at that, second to Ceres (Dwarf Planet) and there is a possibility that it might be added to dwarf planet status in the near future once it's shape has been confirmed.
Vesta - formally known as 4 Vesta. It is an asteroid in the asteroid belt and was thought to be part of a protoplanet. (although the existence of any sort of planet existing, is under debate). It is the second largest object in the asteroid belt, after Ceres the dwarf planet [See related link].
According to the US naval astronomical applications department the 3rd largest asteroid body is called 4 Vesta. Ref: http://aa.usno.navy.mil/faq/docs/asteroid_masses Actually, they do not know what the largest asteroid is since Pallas and Vesta both have been designated as the second largest asteroid after Ceres, which is no longer an asteroid. Since Ceres is a dwarf planet now, Pallas or Vesta is the largest now. Since Ceres is a dwarf planet, the third largest asteroid is Hygiea now. Pallas and Vesta are the top two largest asteroids now. Vesta is more massive than Pallas, though.
The mean radius of the asteroid Vesta is about 262.7 kilometers (163.2 miles).
Depending on what you view as an asteroid. The second largest non-Dwarf Planet KBO is 2007 OR 10 (this is a fairly newly discovered object and is based on some guesswork) falling just behind Sedna. The second largest non-Dwarf Planet in the main asteroid belt is Vesta which falls only slightly behind Pallas. However, Vesta has more mass.
Ceres, now classified as a dwarf planet, is by far the largest asteroid.If Ceres is not considered, the asteroid Vesta, about 1/4 the mass of Ceres, is the largest asteroid. Both these and most other larger asteroids are located in the main Belt between Mars and Jupiter.

An asteroid is a minor planet that can lean towards terrestrial objects such as the rocky protoplanet-asteroids of Vesta and Pallas.

Triton is one of the moons of Neptune. Ceres used to be an asteroid, but has now been recategorized as a "dwarf planet". Pallas and Vesta are asteroids.

Vesta is the only Asteroid visible on Earth by the naked eye. It has no moons
Ceres, now classified as a dwarf planet, is by far the largest asteroid.If Ceres is not considered, the asteroid Vesta, about 1/4 the mass of Ceres, is the largest asteroid. Both these and most other larger asteroids are located in the main Belt between Mars and Jupiter.
A day on Vesta, which is a large asteroid located in the asteroid belt between Mars and Jupiter, lasts about 5.34 hours.
The two largest asteroids in the asteroid belt are Ceres, which is also classified as a dwarf planet, and Vesta. Ceres is the largest asteroid, with a diameter of about 590 miles, while Vesta is the second largest, with a diameter of about 326 miles.
There is only one asteroid currently visible to the naked eye. It is the Vesta asteroid.
