HD21749c revolves around the star HD 21749 entries, located in the constellation Grid that at a distance of 52 light years from our planet. HD21749c sizes comparable to the size of the Earth. HD21749c revolves around the parent star once every 7.8 day, the temperature on the planet’s surface is about 425 degrees Celsius (slightly smaller than Venus).
HD21749c is the second exoplanet discovered in the course of the mission, TESS. The first was a planet in the system PI table Mountain, located 60 light years from Earth.
Telescope TESS (Transiting Exoplanet Survey Satellite) has replaced the space Observatory “Kepler”, launched in March 2009 and over the course of his work discovered more than two thousand exoplanets and binary stars 2165.
TESS is looking for extrasolar planets by transit photometry method in all directions relative to the Earth. The search area consists of 26 segments, each of which chambers will be observed for 27 days, fixing the brightness of individual stars every two minutes.
Open extrasolar planets TESS will be examined in subsequent missions. In particular, they will analyze using the “James Webb” the most powerful space telescope in the world, which will launch in the next decade.
