NASA discover 'Three Alien Planets' smaller than Earth

Last November, I shared a post from a discovery by NASA about a planet Kepler-21b, a new planet that's close to the size of earth and is only about 352 light years away. Then there was an armature astronomer, who with the use of his 'homely gadgets' found a new solar system - something that even baffled the people at NASA.
Now the news is that NASA has discovered not one and not even two, but three alien planets, smaller than our earth.

Using the data from NASA’s Kepler mission, astronomers have found three alien planets smaller than Earth, orbiting a star much smaller than our Sun.

The planets, which are orbiting a red dwarf star known as KOI-961, are 0.78, 0.73 and 0.57 times the diameter of Earth, making them the smallest alien planets discovered so far.

The KOI-961 is located 120 light-years away, in the Constellation Cygnus (The Swan). It’s approximately one-sixth the size of our sun, which made it possible for scientists to watch for dips in the star’s brightness and thus discover the orbiting planets.
