Name the newborn planet in our galaxy ? |
|
Answer» Answer: An exoplanet or EXTRASOLAR planet is a planet outside the Solar System. The first possible evidence of an exoplanet was noted in 1917, but was not recognized as such.[4] The first confirmation of detection occurred in 1992. This was followed by the confirmation of a DIFFERENT planet, originally detected in 1988. As of 1 February 2020, there are 4,173 confirmed exoplanets in 3,096 systems, with 678 systems having more than one planet.[5] There are many methods of detecting exoplanets. Transit photometry and Doppler spectroscopy have found the most, but these methods suffer from a clear observational BIAS favoring the detection of planets near the star; thus, 85% of the exoplanets detected are inside the tidal locking zone.[6] In several cases, multiple planets have been observed around a star.[7] About 1 in 5 Sun-like stars[a] have an "Earth-sized"[b] planet in the habitable zone.[c][8][9] Assuming there are 200 billion stars in the Milky Way,[d] it can be hypothesized that there are 11 billion potentially habitable Earth-sized planets in the Milky Way, RISING to 40 billion if planets orbiting the numerous red dwarfs are included.[10] |
