Final answer:
Asteroid A, with a mass of 16,000 kg, is twice as heavy as Asteroid B, which has a mass of 8,000 kg.
Step-by-step explanation:
The mass of Asteroid A is 16,000 kg, and the mass of Asteroid B is 8,000 kg. Therefore, the mass of Asteroid A is twice the mass of Asteroid B. To put this into context, asteroids in space can vary greatly in size and mass. The large ones, such as Ceres, Pallas, and Vesta, make up a significant portion of the total mass in an asteroid belt.
For example, these three asteroids, with their respective diameters and assumed density, can be used to estimate the mass of larger objects within the belt. By calculating their individual masses and then multiplying the result by two, researchers can estimate the mass of the entire asteroid belt.
