Solar system and atom theory? A single atom has a shield and electron around it. The farther the shield, the weaker the attraction of electron. So how about the sun and the planet. Is it the same theory?

Question

What is the Oort Cloud?

Levi Anderson · Accepted Answer

The Oort Cloud is a region of space occupied by long period comets, dust, grit and bits way beyond the orbit of Pluto.

It is still part of the solar system, but very weakly bound to the Sun.

Owen Atkinson · Answer

There are some parallel ideas, but it isn’t the same theory. Saying that, the connection you have spotted caused some excitement among the scientific community at the time.

The force on a planet is given by Newton’s universal law of gravitation (#F = -G.(m_1.m_2)/r^2#) The force on an electron circling the nucleus is given by #F = 1/(4pi epsilon_0)(q_1.q_2)/r^2# Although they are not the same, they are comparable in that they both vary inversely with squared distance; mass causes gravitational attraction, while charge causes electrostatic attraction.

Luca de · Answer

undefined In the solar system, the planets remain in orbit around the sun due to the immense gravitational pull of the sun, which decreases with distance in accordance with Newton's law of universal gravitation. However, unlike the interaction between an atom's electron and nucleus, the solar system's planets and sun are subject to gravity, not electrostatic forces.
