与太阳的距离

简介 981光年. 穿越它需要:

  • 光981年
  • 旅行者1号的速度17.4百万年
  • 以100 km/h的速度行驶10.6亿年

旅行者1号以截至2026-10-25的一年中向外运动的速度(JPL Horizons)。驾车:不停歇,永不加油。

概况

  • 开普勒-62 e的平衡温度介于−50至+50 °C之间。

发现方式

  • 2013年通过凌星法发现首颗行星(NASA系外行星档案库)。

它的行星

  • Kepler-62 b — 1.3 times Earth's width, about Earth-sized — probably rocky; its year lasts 6 days; about 480 °C, hotter than boiling water; found in 2013 by transit.
  • Kepler-62 d — 2 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 18 days; about 240 °C, hotter than boiling water; found in 2013 by transit.
  • Kepler-62 e — 1.6 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 120 days; about −3 °C, below freezing; found in 2013 by transit.
  • Kepler-62 f — 1.4 times Earth's width, about Earth-sized — probably rocky; its year lasts 270 days; about −65 °C, below freezing; found in 2013 by transit.
  • Kepler-62 c — 0.5 times Earth's width, smaller than the Earth; its year lasts 12 days; about 310 °C, hotter than boiling water; found in 2013 by transit.
