Equilibrium temperature and distance to the Sun for planets currently known within 5 pc from the Solar System. Equilibrium temperatures were computed assuming circular orbits for all objects, and a Bond albedo of 0.3. Data were obtained from the exoplanets.eu (Schneider et al. 2011) website whenever available. The parameters of the planets are reported in Anglada-Escudé et al. (2014, 2016), Ribas et al. (2018), Hatzes et al. (2000), Benedict et al. (2006), Bonfils et al. (2018), Howard et al. (2014), Feng et al. (2017, 2018), Astudillo-Defru et al. (2017b,c), Burt et al. (2014), Correia et al. (2010), Rivera et al. (2010), Jenkins et al. (2014), Wittenmyer et al. (2014). The limits of thehabitable zone for a star like Gl 411 are indicated by green dotted lines. The symbol sizes are proportional to the natural logarithm of the minimum mass.
