Asteroids come in all shapes and sizes, and now astronomers have observed an asteroid called Pallas, named after the Greek goddess of wisdom, and was originally found in 1802. Astronomers have analyzed the asteroid’s shape and surface using Spectro-Polarimetric High-contrast Exoplanet Research (SPHERE) imager on the Very Large Telescope in the Atacama Desert of northern Chile. Astronomers then developed a 3D model of Pallas and observed that the object is denser than the dwarf planet Ceres but less dense than Vesta, as the second-largest known asteroid. The finding indicates that Pallas possesses a greater proportion of rock to ice than Ceres and astronomers are now keen to focus on other asteroids observed by VLT/SPHERE in the future.
