If gravity is intrinsically so weak compared to the strong force, why do we say that gravity rather than the strong force keeps the planets in orbit around the Sun?

Use the basic classification method: Nucleophilicity the measure how good a Nucleophile is governed by the following. The ability to give away an electron and bond: 1) Charge 2) Polarizability...

We know because of all the data collected by scientist and satellites. But there are some observations you can do to determine for yourself what orbits what. 1 / Let's...

No scientist seriously doubts the heliocentric theory, indeed evidence of it is available to anyone with a decent phone or very modest telescope and a few clear nights to observe...

This is only an approximation to the period, using Kepler's third (empirical) law for approximating the period..

The Moon is on average only about 380,000 km away. The nearest any other planet comes to Earth is about 100 times that far (Venus). This makes a big difference...

A good approximation for the obits of planets is to use Kepler's laws of planetary motion. To calculate the distances using Kepler's laws you first of all need to know...

In the solar system, the star Sun's mass is the same for all orbiters. So, the centripetal acceleration is inversely proportional to the square of the distance. The proportion...

Although no planet orbits in a perfect circle, most planets orbit in a slightly elliptical orbit, only slightly out of round. Mercury is the exception as it has a highly...

Refer Science Magazine articles by discoverers. The orbit period might be much higher than Neptune's 165 years for this far-beyond Neptune planet.
