Select all the correct answers. Suppose a team of astronomers recently discovered a solar system similar to our own, but in an earlier stage of
development. Based on how the planets of our solar system formed, which two observations would you expect the
astronomers to make?

- dense, rocky objects near the central star
- thick clouds of liquid helium orbiting near the central star
- planetesimals orbiting in different directions around the central star
- clusters of rock loosely held together by gravity
- the rate of rotation slowing down for all objects
