General Awareness Questions
Q. How many Earth- sized Exoplanets have been discovered by NASA around a single star in February 2017?
NASA announced a Seven new systems of Exoplanets, which are Earth-size, and could potentially hold life. These exoplanets are located outside of our solar system and orbit a star. NASA has named the system of planets after the â€˜Transiting Planets and Planetesimals Small Telescope,â€™ which is located in Chile. This telescope first discovered three of the planets in this system in May 2016. Unlike Earth, which rotates on its axis, the planets are â€œtidally locked to the star.â€ This means that one side of the planet has the only a day, and one side has only a night. It also means the weather conditions are unlike what we experience on Earth.
