The BBC are reporting on some planets which have been found;
BBC News - First Earth-sized planets spotted
In it they say; "They are both much closer to their star than the Earth is to the Sun and so they complete an orbit much more quickly: 20e circles its star in just six days, 20f completes an orbit in 20 days whereas the Earth takes a year."
Surely a year is defined by how long the planet takes to orbit its sun, so they all take a year, there just may be a different amount of days in the year. And do they mean 6 of its days or the equivalent of 6 earth days?
Or is it late at night and I'm missing something?
