The Dec 17/24/31 issue has a short article in the "Comment" section by Stephen Baxter discussing the hunt for exotic exoplanets. He argues that SF predicted what we call "super-Earths", and cites Big Planet in the fourth paragraph. "Jack Vance's Big Planet (1952) is probably the most famous example." He mentions the science, and thenĀ "The appeal is the romance of huge landscapes, coupled with the basic plausibility of the planet's defining numbers..."

BTW, New Scientist is the best science magazine in the English language, IMHO.
