Any model of the origin of the solar system must explain why all the planets orbit the Sun in the same direction and in nearly the same plane. One model that wasdevisedexplicitly to address this issue was the tidal hypothesis, proposed in the early 1900s.Two nearby planets, stars,...
Learning practice- use what you know to answer questions about when our solar system was formed and what scientists think caused it Additional Learning To find out more about the sun and other details about our solar system, read the lesson titled Formation of the Solar System: Lesson for Kid...
The temperature, reaction rate, pressure, and density increased until hydrostatic equilibrium was achieved. At this point, the Sun became a main-sequence star. Solar wind from the Sun created the heliosphere and swept away the remaining gas and dust from the protoplanetary disc into interstellar ...

creating the matter and energy that would be the solar system, as well as time itself. It was during this explosion that gravity was created and the exact formation and orbit of each planet was set. According to this theory, the shape, orbit and chemical makeup of the earth is affected ...
In his experiments with gravity, Isaac Newton showed how the motion of each planet in the solar system results from the combined gravitational pull of the Sun and of all the other planets, each contributing according to their mass and distance from the others. 选项: A、of all the other plan...
