A study describing the three planetswas published this week in the journal Astronomy & Astrophysics.科學(xué)家發(fā)現(xiàn)了數(shù)顆圍繞著長(zhǎng)蛇座M矮星GJ 357運(yùn)行的系外行星，系外行星指的是圍繞太陽(yáng)系外恒星運(yùn)行的行星。這顆恒星的溫度比太陽(yáng)低40%， 質(zhì)量和體積只有太陽(yáng)的三分之一左右。一項(xiàng)描述這三顆行星的研究本周發(fā)

4、表在天文學(xué)與天體物理學(xué)期刊上。The first exoplanet discovered around the star was GJ 357 b.科學(xué)家發(fā)現(xiàn)的首顆圍繞這顆恒星運(yùn)行的系外行星是GJ 357 b。The exoplanet is 22% larger and 80% more massive thanEarth ， making it a super-Earth. Theresearchers estimate that it has an average temperature of 490 degrees Fahrenheit. Itcompletes one orbit

5、around the star every 3.9 days.這顆系外行星體積比地球大22%，質(zhì)量比地球高80%，使之成為“超 級(jí)地球” 。研究人員估計(jì)它的平均溫度為490 華氏度（約合 254 攝氏度） 。這顆行星的公轉(zhuǎn)周期為3.9 天。 Wedescribe GJ 357 b as a hot Earth ， said Enric Pall e , study co-author and astrophysicist atthe Institute of Astrophysics of the Canary Islands. Although it cannot host life ， i
