I get a blackbody temperature of 437 K (=164 C) at 0.09 AU, not so great unless you like a hot-water setup as Hal Clement envisions in his Close to Critical...myself, i think sulfuric acid – graywyvern
Dhrawn. From Wikipedia, the free encyclopedia Star Light is a science fictionnovel by Hal Clement.
This is undoubtedly the model of lippincott: (1960) which concludes 10 Mj at 8.0 years & 0.30 ecc Clement's solid-superjovian would have a mass of about 3471, a radius of 9.3, & a gravity of 40.6 times Earth's (he says "forty"). Surface pressure 26.6 atmospheres, & a solar day of two months. – graywyvern
It is the sequel to one of Clement's earlier books, Mission of Gravity.
The novel was serialized in four parts in Analog Science Fiction/Science Fact Magazine from June to September 1970. Star Light was first published as a paperback book by Ballantine Books in September 1971. Plot summary The story is set several decades after the events of Mission of Gravity. Gatewood's planets. Table of Contents This web page is an attempt to provide a review of humankind's quest for the discovery of planets outside our Solar System.
In addition, a series of major web sites dealing with the search for extrasolar planets are listed. They are as follows: In addition to the above sites, NASA's Origins Program is attempting to answer an important question (among others), Are there worlds like the Earth around nearby stars? Jude rook does the math. Here are life zone and planetary year calculations for a couple of nearby stars, one much smaller and cooler than Sol, one much larger and hotter.
Lalande 21185: Here is a link to some basic data on this red dwarf star. As it seems to have a luminosity of only 0.025 (two and a half percent of Sol’s), its life zone is a lot closer and narrower, ranging from 0.11 AU on the inside to 0.24 on the outside. Earth twin distance comes out to 0.16. An Earth twin’s “year” would be around 23 days long. Another set of planet names. On DeviantArt. The poster. The sculpture installation.

Ormazd. A novel in English. A novel in Polish. Miło mnie ZASKOCZYŁA po latach lektura tej debiutanckiej powieści Janusza Zajdla.
Powstała na początku lat 60, napisana została i niejako sformatowana wybitnie pod czytelnika młodego, głodnego kosmicznych przygód, przedstawionych mu w przystępny i - jak się okazuje nawet teraz, po 50 blisko latach - w zupełnie NIEBANALNY sposób. Pióro Zajdla, w tak wczesnym dla niego etapie kariery pisarza SF, odnaleźć tutaj możemy lekkim a precyzyjnym już wielce! Całkiem ciekawa fabuła - z perspektywy czasu zapewne mocno teraz oklepana - okraszona została być może i infantylnymi chwilami dialogami dość prostych w konstrukcji bohaterów, ale.. A painting.

We’re out in space, though in astronomical terms, not too far away. Our setting takes us to the star ‘Lalande 21185’. It’s only 8.1 light-years away from here, not quite twice the distance to the closest star, Alpha Centauri. This star is much cooler and smaller than our Sun, about half the diameter and only 10% of the brightness. It’s a type of star known as a ‘Red Dwarf’. The prezi. Van de Kamp.

David darling. The fourth nearest star system to the Sun after Alpha Centauri, Barnard's Star, and Wolf 359.
Lalande 21185 is located in the southeastern corner of Ursa Major, northwest of Alula Borealis (Nu UMa). It is about three times too faint to be seen with the unaided eye. Although Lalande 21185 is almost 200 times dimmer than the Sun, it is among the brightest red dwarfs in the solar neighborhood. In my personal mythology. On solstation. Lalande 21185 is the fourth system closest to Sol after Alpha Centauri 3, Barnard's Star, and Wolf 359.
The star is located only about 8.3 light-years away in the southeastern corner (11:03:20.19+35:58:11.55, ICRS 2000.0) of Constellation Ursa Major, the Great Bear which also encompasses the Big Dipper -- northwest of Alula Borealis (Nu Ursae Majoris). It is about three times too faint to be seen with the naked eye. NASA -- larger image.
