Jumping the interstellar shark here a bit
Reviewed in the United States on September 6, 2020
This is the first in this series by the same author and illustrator that just seems like they spitballed ideas to add another book to sell as opposed to something that is fun to read/sing and from which kids can acquire vocab. The words no longer fit in the traditional song structure (try singing "There was an old astronaut who swallowed a meteoroid" and you'll see what I mean) and the interstellar objects could have been better thought out and selected (explaining the distinction between a comet and meteoroid--both of which are things the old astronaut swallows in the book--to a toddler was not easy, and I took an introductory astronomy course in college). One redeeming aspect is that each page contains a little fact about the object on the page in a rhyming two-sentence blurb, and those were the main items I focused on while reading the book.
In sum, I strongly recommend other books in this series, but not this particular one.
