Science · True or False?
The answer is False.
The Sun and the planets actually formed together from the same solar nebula, a giant cloud of gas and dust that collapsed under its own gravity about 4.6 billion years ago. As the cloud contracted, it spun faster and flattened into a protoplanetary disk due to the conservation of angular momentum, with most of the mass collecting at the center to form the Sun and the remaining material clumping together into the planets.
