If the radius of the Earth's orbit around the Sun is 150 million km, what is the speed of the Earth?
$F_g = F_c$ $F_g=(G M_(sun) M_(earth))/(R^2)$ Newton gravitation law where $G=6.67*10^(-11) m^3/(kg*s)$, $R=1.5 *10^11 m, M_(sun)=2*10^30$ $(G M_(sun) M_(earth))/(R^2)=M_(earth)v^2/R$ $v^2=G M_(sun)/R$ $v=29.8 (km)/s$ $v_(mean)=29,783 (km)/s$ sorce:

Does the earth orbit the sun? Or does the sun orbit the earth? How do we know?
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...

Do planets actually revolve around the sun? Maybe they follow the sun around a more central Star in middle of Galaxy? Based on the heliocentric model of orbiting, how could the planets revolve around the sun this way, if this it were true?
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...

What is keeping the Earth's degree of tilt in its orbit around the Sun and why doesn't the Earth wobble? When was the last time the Earth's degree of tilt changed?
The Earth's tilt axis , or obliquity, is changing continuously over a 41,000 year cycle. The angle of tilt varies between 22.1 and 24.5 degrees. It is currently at 23.44...

Why does the tilt of the earth affect the amount of light and therefore the seasons?
How are the seasons affected by the tilt of the equator?
First of all 's axial tilt angle and direction are constantly changing due to precession. These effects are small and are only noticeable over long periods of time. We will...

What does the tilt of the earth have to do with why the earth revolves around the sun?
The tilt of affects weather patterns and gives us the seasons, but our "trip" around is not affected by the tilt. If Earth stopped spinning around its axis it would...

Pluto's orbital semi-major axis is 39.48 times larger than that of Earth. According to Kepler's third law, how long is the period of its orbit around the Sun?
This is only an approximation to the period, using Kepler's third (empirical) law for approximating the period..

If you take millions of tons of metal off the earth in the form of satellites therefore reducing earth's specific mass, would this in turn affect the earth's orbit around the sun?
Our estimates are from scientific computation. The precision (the number of correct significant digits (sd), in scientific notation) cannot be more than the smallest among the sd in the...

If diameter of Earth changed to 120,536 km, would its distance from the Sun, axial tilt, and rotation rate change?
First of all, you are suggesting increases its mass by a factor of 10. How does that happen? The answer to that question is critical because it impacts Newton's...

Assuming that the Earth is a sphere and its orbit around the Sun is a circle, how do you find the volume of the torus that is just sufficient to accommodate the Earth?
The volume of the torus is $2pi^2(orbit radius)(Earth radius)^2 cubic units $=2pi^2(1495987871)(6378)^2 cubic km $=1.201 X 10^17$ cubic km $=$120100000$ billion cubic lm To accommodate Luna also in this this...
