How to say "crater" in Japanese

• クレーターCommon
  nounThe everyday word for a crater as a landform: a bowl-shaped depression on the moon or a planet, or one left by an explosion or impact. This is almost always the word you want for the common sense of 'crater'.
• コップ座コップざ
  nounA less common term for Crater (the Cup), the southern constellation named after a cup, not a landform. It is a marginal match for 'crater' and never the right word for a physical crater.

Use 「クレーター」 for an actual crater, such as on the moon or from an explosion; 「コップ座」 refers only to the constellation Crater (the Cup), not the landform sense.
