State whether the following statements are true or false and justify your answer.1) Pole star is a member of the solar system.2) Mercury is the smallest planet of the solar system.3) Uranus is the farthest planet in the solar system.4) INSAT is an artificial satellite.5) There are nine planets in the solar system.6) The constellation named Orion can be seen only with a telescope.

False. The Pole Star, also known as Polaris, is not a member of the solar system. It is actually a bright star located at the end of the handle of the Little Dipper (Ursa Minor) constellation. The solar system consists of the Sun, planets, moons, asteroids, comets, and other celestial bodies gravitationally bound to the Sun.

False. Mercury is not the smallest planet in the solar system. That title goes to Pluto, which was considered the ninth planet until its reclassification as a dwarf planet by the International Astronomical Union (IAU) in 2006. Mercury is the smallest of the eight recognized planets in the solar system.

False. Uranus is not the farthest planet in the solar system. Neptune holds that position. The order of planets in the solar system, from closest to farthest from the Sun, is Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

True. INSAT stands for Indian National Satellite System. It is a series of multipurpose geostationary satellites launched by the Indian Space Research Organisation (ISRO) to serve various telecommunications, broadcasting, meteorology, and search and rescue applications. As artificial satellites, they are man-made and placed in orbit around the Earth.

False. As of my last update in September 2021, there are eight recognized planets in the solar system. In 2006, the IAU redefined the criteria for what constitutes a planet and reclassified Pluto as a dwarf planet, reducing the number of recognized planets to eight. The eight planets in the solar system, in order from the Sun, are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

False. The constellation named Orion is visible to the naked eye and can be seen without the need for a telescope. Orion is one of the most prominent and recognizable constellations in the night sky, known for its distinctive pattern of stars, including the three bright stars in Orion's Belt. It is visible from various parts of the world and is best seen during the winter months in the Northern Hemisphere and the summer months in the Southern Hemisphere.
