can the moon change its movement in 3 day's,im a security gaurd at nite,i've seen it in a differant spot,3 nites in a row,one nite it rotated and went down in 2 hour's,this is not normal

[derekowens]

@trx125tracy69 Well, the moon should rise and set about 50 minutes later each day, so it should appear in a bit different spot each night, if observed at the same time from night to night. You should not see it rotate, though. The same side of the moon always faces the earth.

3:54 Does not show Earths rise, aprox. it's a less than half of distance you showed.

[derekowens]

@Benuliukas Can you elaborate on that a bit? I'd like to check the math, etc. if I need to. Thanks, DO.

dont know why but i feel like moon is not that far from earth when i look at the moon

[derekowens]

@Angles786 That's actually really interesting. I've heard stories of people groups who thought the moon was really *really* close, like just above the tree tops. When I look at the moon, I find it believable that people could think it was really close if they weren't schooled to think otherwise.

@outled Well, the planets orbit the sun. Neils Bohr, in the early 1900's, hypothesized that the electrons orbit the nucleus of the atom in a similar manner, and this became known as the "Bohr model" of the atom. Today we don't think that are actually orbits. Instead, we think that there are regions of space around the nucleus where the electron is more or less likely to be at any given moment, and equations of probability are used to describe their likely location.

[outled]

do you ever think that planets are like atoms? its the only way i can understand space. :)

[staranjela]

really informative and interesting

woow...

wow, im glad i found this video. thx 4 posting. great comilation of earth-moon-sun scince facts nice too hear all in one place at the same time.

@akilisatolitot impossible, the moon goes away from earth. each year it travels the distance of a thumb away from earth, 80million years ago the moon was 40.000 kilometers closer and looked extremely huge. you got a positive or a negative type of orbit, positive orbits get closer, the moon is a negative orbit because when Theia and Earth collided a mixture of the planets cores (the moon) popped out and got blasted into space. because it was pushed away it will keep moving away further...

[Gardureth]

This is finaly the exact answer i needed thank you a million times

[akilisatolitot]

that would be scary if the moon hits the earth accidentally.....

[akilisatolitot]

the earth is the sun's moon and the earth is the moon's sun and the moon is the earth...haha,,,you guys got me???

[MediocrityAbounds]

great job

[individni]

Thank you, this was what i was looking for.

your video rocks brother!
