newly forming stars are surrounded by gas and dust. based on this observation--and your previous observations about the relative orbits, positions, and sizes of the planets--what is the most likely scenario for the formation of the solar system? choose one: a. a cloud of gas and dust collapsed into a spherical shape, within which the sun and planets formed. b. two stars collided and broke apart to form the sun and the planets. c. the sun formed by itself from a collapsing cloud of gas and dust, then later gravitationally captured the planets as they happened to pass by. d. a cloud of gas and dust collapsed into a flattened disk, within which the sun and planets formed.
