月亮大还是星星大
我们能够肉眼观察到的星星比月亮大。看上去月亮的视直径要远大于其它的星星,因为月亮离我们太近。但实际上,能够肉眼观察到星星都要比月亮大。我们看到的星星基本是恒星,恒星肯定是比月亮大的。
The stars we can see with the naked eye are bigger than the moon. It seems that the apparent diameter of the moon is much larger than that of other stars, because the moon is too close to us. But in fact, the stars are bigger than the moon. The stars we see are basically stars, and the stars must be bigger than the moon.

1、看上去月亮的视直径要远大于其它的星星,因为月亮离我们太近。但实际上,我们看到的大部分星星都要比月亮大。
1. It seems that the apparent diameter of the moon is much larger than that of other stars, because the moon is too close to us. But in fact, most of the stars we see are bigger than the moon.
2、因为我们看到的星星基本是恒星,恒星肯定是比月亮大的。而我们肉眼看到的行星也是比月亮大的。
2. Because the stars we see are basically stars, the stars must be bigger than the moon. The planets we see with the naked eye are also larger than the moon.
3、月球的直径约是3500公里,你肉眼能看到的星星有一些是太阳系的行星,水星赤道半径2440 千米就比月球小。火星赤道半径3398 千米跟月球差不多,金星赤道半径6052千米就比月球大;另外的土星木星都是巨行星,都比月球大的;还有的远日行星,天王星海王星你肉眼是眼不到了,但是体积也比月球大。
3. The diameter of the moon is about 3500 kilometers. Some of the stars you can see with the naked eye are planets of the solar system. Mercury's equatorial radius of 2440 kilometers is **aller than the moon. The equatorial radius of Mars is 3398 kilometers, which is about the same as that of the moon, while the equatorial radius of Venus is 6052 kilometers, which is larger than that of the moon; The other Saturn and Jupiter are giant planets, larger than the moon; There are also distant planets, Uranus and Neptune, which are invisible to the naked eye, but also larger than the moon.
月球的直径约为地球直径的3/11,表面积大约是地球表面面积的1/14,比亚洲面积稍小。月球的体积只相当于地球体积的1/49,质量约等于地球的1/81.3。月面上自由落体的重力加速度为1.62米/秒,为地球上表面重力加速度的1/6,所以同一种物质在地球上称得的重量是月球上称得的1重量的6倍。
The diameter of the moon is about 3/11 of the earth's diameter, and its surface area is about 1/14 of the earth's surface area, which is slightly **aller than that of Asia. The volume of the moon is only 1/49 of the volume of the earth, and its mass is about 1/81.3 of the earth. The gravity acceleration of a free-falling body on the moon surface is 1.62 meters/second, which is 1/6 of the gravity acceleration of the earth's surface. Therefore, the weight of the same material on the earth is 6 times that of the weight on the moon.
