Why do astronomers refer to carbonaceous chondrites as unmodified or "primitive" material?
The Tunguska asteroid is estimated to have had a diameter of 50 m, and to have produced an explosion equivalent to 10 megatons of TNT (1 megaton = 4.2 x 1015 joules). Assume that the asteroid was a sphere with density 2 g/cm3. Using the kinetic energy formula K = ½ mv2, where m is the mass and v is the speed, to estimate the speed of the asteroid. Assume that all kinetic energy is converted into the energy of the explosion.

You decide to go on an interstellar mission to explore some of the newly discovered extrasolar
planets orbiting the star ROTOR. Your spacecraft arrives in the new system, in which there are
five planets. ROTOR is identical to the Sun (in terms of its size, mass, age and composition). From
your observations of these planets, you collect the following data:

- Consider the differentiated meteorites. We think the irons are from the cores, the stony-irons are from the interfaces between mantles and cores, and the stones are from the mantles of their differentiated parent bodies.
