Introduction to Asteroid Bennu
Asteroid Bennu is a near-Earth asteroid that has been the subject of extensive study in recent years. It is a small, irregularly shaped asteroid that is approximately 1.1 kilometers in diameter. Bennu is a potentially hazardous asteroid, meaning that it has a close approach to Earth and could potentially impact our planet in the future.
Physical Characteristics of Bennu
Bennu is a carbonaceous asteroid, meaning that it is composed primarily of carbon-rich materials such as organic compounds and water. It has a highly irregular shape, with a surface that is characterized by numerous boulders and craters. Bennu's surface is also covered in a layer of regolith, which is a type of loose, fragmented rock that is common on asteroids.
Diameter of Bennu
The diameter of Bennu is approximately 1.1 kilometers, which is significantly larger than the options listed in the question. This means that the correct answer is not among the options listed.
Comparison with Other Asteroids
To put Bennu's size into perspective, it is worth comparing it to other asteroids in our solar system. For example, the asteroid Vesta is approximately 530 kilometers in diameter, while the asteroid Ceres is approximately 950 kilometers in diameter. Bennu is significantly smaller than these asteroids, but it is still a large and complex object that is worthy of study.
Importance of Studying Bennu
Studying Bennu is important for a number of reasons. First, it provides valuable insights into the formation and evolution of our solar system. Bennu is a remnant from the early days of the solar system, and its composition and structure can provide clues about the conditions that existed during this time. Second, studying Bennu can help us better understand the risks associated with near-Earth asteroids. By studying Bennu's orbit and composition, we can gain a better understanding of the potential risks associated with asteroids like it.
Conclusion
In conclusion, the diameter of the asteroid Bennu is approximately 1.1 kilometers, which is significantly larger than the options listed in the question. Studying Bennu is important for a number of reasons, including gaining insights into the formation and evolution of our solar system and better understanding the risks associated with near-Earth asteroids.

A: The name "Bennu" comes from the ancient Egyptian god of creation and rebirth, Bennu. The name was chosen because Bennu is a symbol of renewal and transformation, reflecting the asteroid's unique composition and complex orbit.
Q: What is the composition of Asteroid Bennu?
A: Bennu is a carbonaceous asteroid, meaning that it is composed primarily of carbon-rich materials such as organic compounds and water. Its surface is also covered in a layer of regolith, which is a type of loose, fragmented rock that is common on asteroids.
Q: What is the size of Asteroid Bennu?
A: The diameter of Bennu is approximately 1.1 kilometers, making it a relatively small asteroid compared to others in our solar system.
Q: What is the orbit of Asteroid Bennu?
A: Bennu's orbit is highly elliptical, taking it from a close approach to Earth to a distant orbit around the Sun. Its closest approach to Earth is approximately 1.4 astronomical units (AU), while its farthest distance is approximately 1.7 AU.
Q: What is the surface temperature of Asteroid Bennu?
A: The surface temperature of Bennu varies greatly depending on its distance from the Sun. At its closest approach, the surface temperature can reach up to 100°C (212°F), while at its farthest distance, it can drop to as low as -100°C (-148°F).
Q: Has Asteroid Bennu been visited by a spacecraft?
A: Yes, the OSIRIS-REx spacecraft visited Bennu in 2018 and 2019, collecting samples and data that will help scientists better understand the asteroid's composition and evolution.
Q: What is the significance of Asteroid Bennu?
A: Bennu is a potentially hazardous asteroid, meaning that it has a close approach to Earth and could potentially impact our planet in the future. Studying Bennu is important for gaining insights into the formation and evolution of our solar system and better understanding the risks associated with near-Earth asteroids.
Q: Can Asteroid Bennu be deflected or destroyed?
A: While it is theoretically possible to deflect or destroy Bennu, it would require a significant amount of energy and resources. The most effective way to mitigate the risk of a Bennu impact is to continue studying the asteroid and developing strategies for deflecting or destroying it if necessary.
