No our Sun is a fully formed Star. A Protostar is gas that is still acreeting matter (still collecting via gravtaional rotation) to form a star. And as a result they are not very bright as they have not condensed enough to start Nuclear Fusion.

The average distance between the Earth and the Sun is about 150 million kilometers. This distance varies due to the elliptical shape of the Earth's orbit.

The difference between the rotation and revoulution is that rotation is the spiinning of the planet on its axis and revoulution is the orbiting of the planet around the sun.
The protosun has not fully "ignited" meaning nuclear fusion is not stably providing the energy output of the star. Once ignition takes place, the central core of the sun will produce energy almost exclusively through fusion, creating enough energy and radiation to slowly wash away the nebulous gas surrounding the protosun revealing the sun itself.

Heat, derived from gravitational energy. The gravitational collapse of the original nebula of gas and dust produced very high temperatures and a "protosun". Eventually the protosun became a star (our Sun) when the nuclear fusion reactions began at temperatures of millions of degrees Celsius.
The name given to the concentration of mass at the center of the solar nebula that eventually formed the Sun is the protosun or solar protostar. This dense core accumulated gas and dust, triggering nuclear fusion to ignite as a star.

The difference between SunIn and lemon SunIn is the addition of some form of lemon.
Soleil, there is no difference between sun and sunshine.

A protosun is a sun (star) that is still forming. It takes millions of years of solar winds and gravitational forces to gather and compress massive clouds of hydrogen to the point where it's gravity is powerful enough to cause nuclear fusion at it's core and "ignite" a new star.
