Question

Some objects in space are created from clouds of gas and dust.

What will happen if the cloud does not have enough mass?

A core will form.
A star will not form.
A protostar will form.
A nebula will not form.

Answer 1

If the cloud does not have enough mass, **a star will not form**. For a star to form, the cloud must have sufficient mass to create the gravitational pressure needed to ignite nuclear fusion in its core. If the mass is too low, the process will not proceed to the point of star formation.
