This paper shows how the conversion of dark matter into ordinary matter (one-dimensional mass into three-dimensional mass) which occurs under a gravitational equilibrium will, when the principal mass is similar to that of the Sun, create a terrestrial planet which has a planetary temperature suitable for the greenhouse effect acting on its gaseous water vapour envelope, to produce a permanent surface liquid water body.  The stellar mass statistics indicate on the assumption that the dark matter conversion process is universal, that this condition is likely to occur.  Hence it is predicted that there are many habitable sister planets to Earth in the Universe.
