Big Bang is the term that describes how the solar system was formed.
Gradually
Gradully
Rapidly
Electrically
Chrmically
D. The sun. All planets in our solar system orbit the sun thus it is the best reference when describing the motion of the planets within that solar system.
The best view of the solar system is that from either of the two Voyager spacecraft which show the solar system from outside. The modern view of the solar system is that there are 8 planets orbiting the Sun. There are also a lot of smaller bodies orbiting the Sun. They are mainly the dwarf planets, asteroids, Kuiper Belt objects, and comets.
The best model to describe atomic structure is the Rutherford model
The answer to that is entirely your opinion.
I think you mean "protoplanet hypothesis". In fact, astronomers usually call it the Nebular Hypothesis A protoplanet is a planet-like object that hasn't fully developed into a planet. Why that hypothesis? It's because it is the best we have to describe the origin of the solar system according to the Laws of Physics.
Best guess; between 4.7 and 4.5 billion years ago.

Not since 1846, no. Everything discovered in the solar system since then is considered to be at best a dwarf planet.
Best answer : the mass of the sun.
