NASA’s TESS satellite has found as many as 2,200 possible planets



The TESS satellite launched by NASA in April 2018 has been working in space for nearly two years.Completed the main task of observing the entire celestial sphere. During this year, TESS discovered as many as 2,200 candidate planets, which is considerably more than the planned target of 1,600. However, because TESS conducts relatively “wide-area” observations, it cannot track specific observation targets for a long time, so only about 120 of them are definite planets. The rest will be more powerful ground-based telescopes or a new generation of space. The telescope has come to take over the work of observation.

Among the planets discovered by TESS, the more distinctive ones include:

.TOI 125 -The first multi-planetary system discovered by TESS includes at least five planets orbiting a host star similar to the sun.

.TOI 1338b -The first planet discovered by TESS to orbit a binary star system. Although this is not the first such system to be discovered, it is still quite rare.

.LHS 3844b -A planet with a revolution period of only 11 hours. Due to the incomparable proximity to the host star, the surface temperature is expected to be as high as 531 degrees Celsius.

.TOI 849b -A dense planet with a mass 40 times that of the Earth but only about 3 times the diameter of the Earth. It is speculated that it may be the core of a gas planet. I don’t know why the atmosphere on the surface has been blown away.

Although TESS has completed its main tasks, it has carried a full 15 years of fuel. As long as the key navigation equipment is still operating normally, TESS will have a long “career” waiting ahead.
