How big is the moon? In the night sky, the moon seems rather small, but in reality, it really isn't. Central Europe would easily fit under it. The surface area of the moon is huge. To give you some perspective, it's as big as the whole European continent, China, the U.S.A., Brazil, and South Africa together.
Weight-wise, the moon is only about 1/81 of the mass of Earth, but how big is it in relation to Earth? Quite big, actually. Our moon is the biggest in the solar system in relation to its planet, and it's the fifth largest moon in the solar system—quite a bit bigger than the dwarf planet Pluto. Now, if the moon is really that huge, how far away is it from us to seem this small in the night sky? Three hundred and seventy kilometers, as far as the ISS maybe? No. At that distance, gravitational forces would rip the moon apart. At 36,000 kilometers, it would be as far away as our most distant satellites.
Let's adjust the distance to reality. Pretty far away, right? A 747 would need 28 straight days to fly to the moon. And even with our current technology, we'd need two full days. And in a car...a lot of time. So, how big is the moon? Well, it kind of depends how you define "big." But seriously though, it's pretty big.
來把那距離調整到實際狀況。滿遠的，對吧？一架 747 飛機會需要整整二十八天來飛到月球。即使有我們現今的科技，我們還是會需要兩天整。而開車的話...需要非常多時間。所以，月球有多大？這個嘛，那有點看你怎麼定義「大」。但講真的，月球滿大的。
Hey, YouTube! We'll try something new this month: Moon May, one video about cool moon stuff each Monday in May. So, see you next week.
