for Thailand National Astronomical Research Institute (Public Organization) (Dr.Dr.), Ministry of Higher Education, Science, Research and Innovation (NHS) organized activities “Nominating Thailand for Planets Outside the Solar System” Promotes Thainess in the Universe and celebrating the 10th anniversary of the National Astronomical Observatory for the general public to nominate a Thai name for a planet outside the solar system, GJ3470b, the first planet outside the solar system that Thai astronomers have studied and researched and observed through telescopes Diameter of 2.4 meters at the Observatory in honor of His Majesty the King’s 7 Cycle Birthday Anniversary or the National Observatory.

Many new discoveries have been made, including new exoplanets. or the discovery of water in the atmosphere of extrasolar planets Demonstrates the potential of Thai astronomers in international astronomy research.
