Three Earth-like planets discovered orbiting dwarf star

An international team of scientists have discovered a trio of Earth-like exoplanets using the TRAPPIST telescope at ESO’s La Silla Observatory.

These planets were found orbiting an ultra-cool dwarf star just 40 light-years from Earth and are likely comparable in size and temperature to Earth and Venus. Scientists have named the ultra-cool dwarf star 2MASS J23062928-0502285 (also known as TRAPPIST-1).

The three planets were found to orbit very close to their host dwarf star. Two of the exoplanets have orbital periods of about 2.4 days and 1.5 days respectively. The third planet has a less well-determined orbital period in the range 4.5 to 73 days.

So let’s do:
1. Scientists discover ______ planets similar to Earth.
