A study reveals details of a violent history of the third largest asteroid


A new study revealed that the Pulse asteroid, which has not yet been visited by a spacecraft, has an unusual violent history that has many effects, probably because of its unusual orbit, in 1802, Palas became the second asteroid ever discovered, named after Pallas Athena, goddess Greek Wisdom, the third largest asteroid, has an estimated size of about 7% of the mass in the asteroid belt in the Solar System.

According to the American “space” website, the average diameter of this asteroid is about 318 miles (513 km), or about 15% of the moon’s diameter.

Much remains unknown about this large asteroid, but a study has shed light on many of Palas secrets, as scientists have used a high-contrast Spectro-Polarimetric extrusion of planets (SPHERE) with a very large telescope in the Atacama Desert in northern Chile to analyze the shape of the asteroid and its surface.

Based on 11 images taken from the surface of Pallas, researchers have discovered that the asteroid is filled with many craters that range between about 18.5 and 75 miles (30 to 120 km).

Their computer simulations also indicate that Pallas has about twice the number of craters found in the largest asteroid, and Miroslav Bros, an astronomer at Charles University in the Czech Republic, said the asteroid’s surface is severely pierced, and its surface may resemble a golf ball.

The researchers also said, that two of the giant pits in Palace, one near its south pole and the other near the equator, indicate that the asteroid has gone through giant effects as the diameter of the shells is between 37 and 65 miles (60 to 90 km).

Computer simulations of previous collisions in the asteroid belt, which were conducted as part of this study, indicate that the objects that affect Palas were also traveling at unusually high speeds, averaging about 252525 miles per hour (41400 km / h), compared to an average speed of about 12 975 (20,880 km / h) for the effects of drilling generation in the asteroid belt.

It is also possible that these high velocities are caused by the way Palas travels in an unusual orbit.
