Morphology

extrasolar = solar (transparent) = extra + solar

The meaning is directly derived from the prefix 'extra' indicating 'outside' and 'solar' relating to the sun, forming 'outside the solar system'.

Etymology

Extrasolar comes from extra- meaning 'outside' and solar meaning 'of the Sun', like the everyday word extra and the word solar. So extrasolar describes something that is 'outside the solar system'.
