But it would take a telescope with the effectivediameter of the sun to actually take photographs of something the size of an elephant strolling on an exoplanet only 4.3 light-years away.
The amount of energy that a flywheel will store for a given change in speed depends on its inertia, which, in turn, depends on its mass and its effectivediameter.
由于速度的特定变化飞轮存储的能量大小取决于其惯性，其惯性反过来取决于飞轮的质量与有效直径。
