if the moon were twice it's size what affect would it have on the earth?

Answer 1

If you mean the moon had twice its present diameter, then it would be 8 times its present volume and mass as the volume of a sphere is 4/3 x pi r^3, This would make it as large as Mars and have several effects

(1) it would retain its atmosphere
(2) larger gravity and huge tides
(3) higher escape velocity
(4) total solar eclipses more frequent and would last longer
(5) lunar clouds would obscure our view of craters
(6) asteroids would be attracted by higher gravity and some might be locked into permanent orbit

Answer 2

If the circumference replaced into doubled, then the radius is likewise doubled. So the exterior is two times as a options from the middle as in the previous. hence, the exterior gravity will change into a million/4 of what it replaced into once, from the inverse sq. regulation. If the mass also more effective with the help of a aspect of two, then the gravity could be doubled because of that. the total gravity could then be a million/4 situations 2 = a million/2. yet ... doubling the linear length makes the volume bypass up with the help of a aspect of 8. So if the density stayed an similar, the mass could bypass up with the help of 8 situations. Then the total gravity could with the help of one million/4 situations 8 = 2 situations what it replaced into once. The rotation promptly each 24 hours, makes in straightforward words a nil.5% huge difference on the equator.

Answer 3

stronger pull on the tides, meaning the tides would be lower, and actually the earths oceans bow out a little bit because the moon pulls on them, so it would make them bow out more, and more light would be reflected from the sun and to the earth so the earth might be warmer at night, but not by much I assume. I cant think of anything else...

Answer 4

Add to the previous list, the fact that a greater sized moon's gravity would emit stronger tidal breaking on the earth's rotation and our days and nights would be much longer now than they presently are.

Answer 5

If the distance is assumed to be unchanged then the affects on earth will be
- periodic rise (tide) and fall (ebb) will be very powerfull
-number of high and low tides will be increased (normally there are two high and two low tides each day)
-sea level will be higher
-land area will be decreased
-tornado and cylclone will frequently be occurred
-climate will be changed
-path of occean current will be changed
-plant growth will be affected
-all events would affect on mental health of human being and other animal

Answer 6

I am guessing that it might collide with earth due to the doubling of its gravity. Well if i'm wrong we still might have to wear sunglasses while driving at night on full moons!

Answer 7

humm higher tides?
