Cách khám phá Hill Sphere 3D Explorer
Open the Hill Sphere 3D Explorer, read r_H ~= a (m/3M)^(1/3) with Earth ~1.5 million km, then confirm the Moon at ~384,400 km sits inside the teal shell.
- Open https://freetoolonline.com/space-3d/hill-sphere.html and wait for the teal Hill shell.
- Read the facts panel: formula, 1.5 million km, 384,400 km, 60,000 km.
- Press Earth and Jupiter to compare shell size.
- Toggle the moon and the moon's own Hill shell.
- Compare with Roche Limit 3D for tidal breakup, or Lagrange Points 3D for L1-L5.
