weighs and maesures

Using powerful  space telescopes NASA scientists have most precise  measurement  every  of a planet  outside our solar system The alien  planet has a mass greater than Earth but less than uranus or Neptune  which make the planet a super-Earth  There are many super Earth in our galaxy  the milky way but  none in our solar  system. from this planet density

scientist  concluded that it is make of iron and rock like  Earth  However this super Earth is too hot  to be habitable  From its closeness to its sun scientist  say its say its surface temperature  must be about  1'400 degrees Fahrenheit  (760 degrees  celsius) meanwhile European  astronomers  hare discovered 16 super Earths and one of these is the right distance from its sun to possibly support  life Researchers also think  the biggest super- Earth might have oceans sooner or later super- Earths may provide the answer to whether there is life elsewhere  in space Our ability to measure precisely objects hundreds of light- year away will be key in solving the mystery . scientist  have now precisely measured  planent beyond our solar system  These exoplanets include some super  Earth with masses bigger than our plant s read about how we measure  things closer in home is this  chapter.
