Planetary atmosphere composition, density, and pressure determine habitability, surface conditions, and human spacefaring feasibility.

ステップバイステップガイド

  1. 1Input planetary parameters: mass, radius, temperature
  2. 2Calculate atmospheric scale height and escape velocity
  3. 3Determine atmospheric retention capability

解いた例

入力
Venus: thick CO₂ atmosphere, 92 atm pressure
結果
Extreme greenhouse effect, surface 464°C
Uninhabitable

避けるべきよくある間違い

  • Assuming all planets have oxygen atmosphere
  • Neglecting atmospheric evolution

よくある質問

What atmospheres can planets retain?

Depends on escape velocity vs. molecular speeds; light molecules escape.
