This would gradually blow away any atmosphere around the planet, leaving in the end about nothing, as happened to Mars. Although the planet may be habitable in the short term, in the longer term it would become difficult to inhabit by human beings. In the near future, both terrestrial and space-based telescopes will allow analyzing the spectrum of planets’ light to ascertain the presence of other chemical elements, such as oxygen. However, with present technologies, it is not possible to detect the presence of a moon around a planet orbiting its star in the habitable zone, nor can one detect the presence of a magnetic field around it.
This list contains three G-class stars and several M-class dwarfs. As we learn more about the formation of planetary systems and we search the neighbouring stellar systems for planets, this list will change. 1. Astronomical observations should be targeted to these star systems to confirm: (1) the presence of planets orbiting the stars in the habitable zone; (2) whether or not these star systems have multiple planets; and (3) the presence in their atmosphere of chemical elements necessary to support life.
Scientists say the Alpha Centauri system, particularly Alpha Centauri B, has the ingredients for an Earth-like planet. Much of its matter is made up of elements heavier than hydrogen and helium, so there would be plenty of heavier material to make planets from. As of October 2012, a planet Alpha Centauri Bb has been discovered. It is Earth-size planet, but it does not lie in the habitable zone within which liquid water can exist. The astronomers who found it say that it is likely there are other planets circling the same star, a little farther away where it may be cool enough for liquid water.
