The second is that encounters between stars are extremelyrare, so rare as to be improbable in the lifetime of the Universe (15billion years).Nebular Hypothesis:A second theory is called the nebular hypothesis.
Nebular Hypothesis - University of Winnipeg
Venus has been referred to as Earths sister planet. The reason forthis is its size, density, and distance from the sun resembles that ofEarth . Therefore, it was once thought thatthe environment on Venus would be similar to that of Earth (especiallysince they formed from about the same position in the solar nebula). SinceVenus is closer to the Sun than the Earth, three things led to the formationof a dense atmosphere on Venus:
A Medley of Potpourri: Nebular hypothesis
Itincorporates many of the components of the nebular hypothesis, but addssome new aspects from modern knowledge of fluids and states of matter.Meanwhile in the inner Solar System:Note that as the planet's began to form they grew in mass by accretingplanetesimals.
How earth was formed in the nebular hypothesis
The early proto-planets areable to sweep the early Solar System clean of large bodies.Notice also that the lighter compounds are vaporized in the inner SolarSystem.

The increase in rotation speed, in turn, must have caused the nebula's to change as it collapsed. In Chapter 11 we saw how a spinning body tends to develop a bulge around its middle. The rapidly spinning nebula behaved in exactly this way. As shown in Figure 15.1, the fragment eventually flattened into a pancake-shaped primitive solar system. If we now suppose that planets formed out of this spinning material, we can already begin to understand the origin of some of the large-scale architecture observed in our planetary system today, such as the circularity of the planets' orbits and the fact that they move in nearly the same plane.
