How can we measure the diameter of an object
WebFor such massive objects, they're still a long way away, so we have come up with some ingenious ways to work out planet sizes. There are several ways that planetary diameters can be measured. The most common is to measure the apparent angular diameter of the planet – how big it looks against the ... WebTo solve this problem, we can measure the circumference of the cup instead.
