与太阳的距离

简介 2,500光年. 穿越它需要:

  • 光2,500年
  • 旅行者1号的速度44.3百万年
  • 以100 km/h的速度行驶26.9亿年

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。

发现方式

  • 2012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-85 d — 1.2 times Earth's width, about Earth-sized — probably rocky; its year lasts 18 days; about 350 °C, hotter than boiling water; found in 2014 by transit.
  • Kepler-85 e — 1.3 times Earth's width, about Earth-sized — probably rocky; its year lasts 25 days; about 290 °C, hotter than boiling water; found in 2014 by transit.
  • Kepler-85 c — 2 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 13 days; about 430 °C, hotter than boiling water; found in 2012 by transit.
  • Kepler-85 b — 1.8 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 8 days; about 540 °C, hotter than boiling water; found in 2012 by transit.
