Based on the star's spectral type of G8V , Tau Ceti's colour and type is yellow main sequence star. answer choices . Tau Ceti's three innermost planets—designated b, c, and d—are probably too hot to support life, being so close to the star that they require only 14, 35, and 94 days to complete an orbit. If Tau Ceti e possesses an Earth-like atmosphere, the surface temperature would be around 68 °C (154 °F). Planet sizes were estimated with a mass-radius relationship. Spica. With a denser atmosphere able to produce a stronger greenhouse effect it could have a much higher temperature, between 0°C and 50°C, enough for complex life to exist. However, if we assume that they are composed of a water-rock mix, their radius might be closer to 1.8 and 2.3 Earth radii, respectively. This means terraforming could easily be done by adding tons of extra greenhouse and buffer gases. Neither yet fit the Earth-like distinction based on the little information we have of them. So it follows that the levels of these elements in Tau Ceti correspond to the levels in Planet f. The actual ratio of magnesium to silicon in Tau Ceti is about 70% greater than that of the sun . For categorization purposes, Hall and Lockwood report that "the terms 'solarlike star', 'solar analog', and 'solar twin' [are] progressively restrictive descriptions". Out of the five possible planets, the two farthest away, Tau Ceti e and f, are potentially habitable. The fifth and outermost planet, designated Tau Ceti f, completes an orbit every 640 days and is slightly closer to its star than Mars is to the sun.
