Question

What did astronomers name the planet they discovered?
Why is temperature a good criterion for searching for Earthlike exoplanets?
What is unique about the size and location of this exoplanet?
Kepler-186f is much closer to its sun than Earth is to its sun. Why is it considered to be in the habitable zone even though it’s so close to a sun?\
Our planet has frozen poles. What property does frozen water have that might be useful in searching for other planets with frozen poles?

Answer:

Explanation:

An exoplanet (extrasolar planet) is a planet located outside the Solar System. The first evidence of an exoplanet was noted as early as 1917, but was not recognized as such until 2016. No planet discovery has yet come from that evidence.[1] However, the first scientific detection of an exoplanet began in 1988. Afterwards, the first confirmed detection came in 1992, with the discovery of several terrestrial-mass planets orbiting the pulsar PSR B1257+12.[2] The first confirmation of an exoplanet orbiting a main-sequence star was made in 1995, when a giant planet was found in a four-day orbit around the nearby star 51 Pegasi. Some exoplanets have been imaged directly by telescopes, but the vast majority have been detected through indirect methods, such as the transit method and the radial-velocity method. As of 3 September 2020, there are 4,330 confirmed exoplanets in 3,200 systems, with 708 systems having more than one planet.[3] This is a list of the most notable discoveries.
