Consider the following statements:1. Asteroids are rocky remnants left...
Statement 1 is correct: Asteroids, sometimes called minor planets, are rocky remnants left over from the early formation of the solar system about 4.6 billion years ago.
- The three broad composition classes of asteroids are C-, S-, and M-types. The C-type (chondrite) asteroids are most common. They probably consist of clay and silicate rocks, and are dark in appearance. They are among the most ancient objects in the solar system. The S-types (“stony”) are made up of silicate materials and nickel-iron. The M-types are metallic (nickel-iron). The asteroids’ compositional differences are related to how far from the Sun they formed.
Statement 2 is not correct: Bennu is a small near-Earth asteroid that passes close to Earth every six years.
- A 4.5 billion-year-old relic of the solar system’s early days, asteroid Bennu has seen it all.
- Bennu’s current composition, according to scientists, was established within 10 million years of the formation of solar system.

Explanation:
Asteroids:
- Asteroids are rocky remnants left over from the early formation of the solar system about 4.6 billion years ago. They are primarily composed of rock and metal.
- Asteroids can vary in size from a few meters to hundreds of kilometers in diameter.
- These space rocks orbit the Sun and are mostly found in the asteroid belt between Mars and Jupiter.
Bennu:
- Bennu is a small near-Earth asteroid that passes close to Earth every year. It is classified as a potentially hazardous asteroid due to its close proximity to our planet.
- NASA's OSIRIS-REx spacecraft visited Bennu and collected samples from its surface to bring back to Earth for further study.
- Bennu is of particular interest to scientists as it could provide valuable insights into the early solar system and the origins of life on Earth.
Correct Answer:
The correct answer is option 'A' - 1 only. Statement 1 is correct as it accurately describes asteroids as rocky remnants from the early solar system. Statement 2 is incorrect as Bennu is not an asteroid that passes close to Earth every year; it is a specific near-Earth asteroid with its own unique characteristics and orbit.
