101955 Bennu is a near-Earth asteroid in the Apollo group. Apollo group asteroids are asteroids that are close to Earth's orbit. Since Bennu is close to the Earth, it has the possibility of hitting the Earth.

Bennu was discovered by the LINEAR Project on September 11, 1999. Bennu is a dark-colored asteroid with an average diameter of 490 meters. Bennu's shape is an irregular sphere. Bennu's surface is covered with impact craters and cracks.

Bennu, which will approach Earth in 2135, is categorically considered a potentially dangerous asteroid. The probability of Bennu hitting the Earth is 1 in 1,750.

Bennu is considered a remnant from the formation of the Solar System. The rocks on Bennu's surface may represent material that formed in the early Solar System.

Bennu was visited by NASA's OSIRIS-REx spacecraft in 2018. The OSIRIS-REx spacecraft collected a 250-gram sample from Bennu and brought it back to Earth. This is the first asteroid sample brought to Earth.

Some technical characteristics of Bennu are as follows: Diameter: 490 meters, Orbital period: 437 days, Orbital radius: 0.92 AU, Mass: 7.8E10 kg Density 1.2 g/cm³, Surface temperature: 220-320 K, Composition: Carbon, silicon, oxygen, iron

Bennu is considered a remnant from the formation of the Solar System. The rocks on Bennu's surface may represent material that formed in the early Solar System.

Bennu's formation occurred about 4.5 billion years ago, during the formation phase of the Solar System. In the early Solar System, Bennu formed from a cloud of dust and gas orbiting the Sun.

This cloud condensed over time to form asteroids, planets and other celestial bodies.

Bennu continued to orbit the Sun after the formation of the Solar System. From time to time, Bennu entered an orbit close to Earth. Bennu's orbit close to Earth increases the probability of hitting the Earth.

Bennu is considered a potentially dangerous asteroid. Bennu will approach Earth in 2135. The probability of Bennu hitting the Earth is 1 in 1,750.

Bennu was visited by NASA in 2018 with the OSIRIS-REx spacecraft. The OSIRIS-REx spacecraft collected a 250-gram sample from Bennu and brought it back to Earth. This is the first asteroid sample brought to Earth.

The sample from Bennu will provide important information about the formation and evolution of the Solar System. The sample will help us understand the composition, formation and evolution of Bennu.

If Bennu hits the Earth, it could cause massive destruction. Bennu's diameter is 490 meters, so if it hits the Earth, it could create a huge crater. Bennu's impact could cause tsunamis, earthquakes and other natural disasters.
