WebOct 9, 2014 · The huge gas-swaddled planet 51 Pegasi b orbits just 7.5 million kilometers from its parent star (a distance about one-eighth the size of Mercury's orbit)—so close, in fact, that its "year" lasts just 4 Earth days or so. Other such "hot Jupiters" orbit their suns even closer than that. WebThe eccentricity of the orbits of 606 extrasolar planets, shown on a logarithmic scale. Note that most orbits are fairly circular, but many are quite elliptical. What do you think the radial velocity curve would look like for elliptical orbits? The physical properties of the known extrasolar planets is also quite interesting.
