The iron meteorite that created Barringer Crater (Arizona) was 50 m in diameter. It caused a crater 1.2 km (1200 m) in diameter, that is, 24 times bigger than the impactor. Keeping in mind that the size of the crater depends on many factors, such as the type of rocks present in the area, estimate the approximate size of the impactor that produced Mare Serenitatis.
Why are there no chondrules in achondritic meteorites?

Group of answer choices
- Meteor showers are not caused by comet debris
- Sun's temperature
- en distribution of debris along comet's orbit
- Earth's rotation axis
