Question

The preferred hypothesis for solar system creation (and the associated steps)

Answer 1

The preferred hypothesis for the creation of the solar system is that it formed 4.5 billion years ago from a rotating cloud of vapor and dust known as the solar nebula. Material within the solar nebula coalesced into planetesimals, which eventually gathered together to form the planets and moons. Comets and asteroids are remnants of the remaining material.

Step-by-step explanation:

The preferred hypothesis for the creation of the solar system is that it formed 4.5 billion years ago from a rotating cloud of vapor and dust known as the solar nebula. As the solar nebula collapsed under its own gravity, material fell towards the center, where it became more concentrated and hot. Increased temperatures in the shrinking nebula vaporized most of the solid material that was originally present.

Regularities among the planets have led astronomers to hypothesize that the Sun and the planets formed together in a giant, spinning cloud of gas and dust called the solar nebula. Within the solar nebula, material first coalesced into planetesimals, which eventually gathered together to form the planets and moons. The remaining material can still be seen as comets and asteroids. This process of planet formation is believed to be similar in other planetary systems as well.

Overall, the formation of the solar system can be summarized as follows:

1. The solar nebula, a rotating cloud of vapor and dust, formed 4.5 billion years ago.
2. The solar nebula collapsed under its own gravity, causing material to fall towards the center.
3. Increasing temperatures in the shrinking nebula vaporized most of the solid material.
4. Material within the solar nebula coalesced into planetesimals.
5. Planetesimals gathered together to form the planets and moons.
6. Comets and asteroids are remnants of the remaining material.
