Rep. Sheila Jackson Lee (D-Texas) stunned attendees at a high school solar eclipse event Monday by claiming the rock-solid moon is a “planet” that is “made up mostly of gases” — before adding she still wants to be “first in line” to learn how to live there.

The former top Democrat on the House Science Committee’s space subcommittee badly botched elementary lunar facts while speaking during the gathering at Booker T. Washington High School in Houston.

“You’ve heard the word ‘full moon.’ Sometimes you need to take the opportunity just to come out and see a full moon is that complete rounded circle, which is made up mostly of gases,” Jackson Lee, 74, told teenage pupils who gathered on a sports field ahead of the rare celestial event.
