A collection of science fiction stories with at least one story for each planet (Pluto has two, and there's a comet story too) from some of the old masters.
My favourites were: Brightside Crossing (of Mercury) by Alan E. Nourse for its evocation of the bloody-mindedness of human explorers; Waterclap (Earth) by Isaac Asimov for the intriguing idea of boiling high presssure water out of a deep sea space instead of forcing it out with even higher pressure air; The Snowbank Orbit (Uranus) by Fritz Leiber about a desparate orbital manouvre. However all of them were of interest to me. ( )

A nice selection of stories written from the early '50s till the early '70s. The theme is simple: 13 stories - One about each of the nine (as we used to say) planets, plus the Sun, the asteroids and comets. Actually, that would be 12 stories, but Pluto gets two short pieces.
The earliest story, "Brightside Crossing" by Alan E. Nourse (1951), is about an expedition to cross the sunward side of Mercury at perihelion... on foot... Back when Mercury was believed to be tidally locked.
The most recent story, "The Comet, the Cairn and the Capsule" by Duncan Lunan (1972), is about a manned mission to examine an unusual comet close-up. They find evidence of intelligence from outside the solar system.
Each story is introduced with up-to-date scientific information (circa 1979).
