1.	Explain the parallax method to measure distance between the earth and planet
Answer» Parallax\xa0is a displacement or difference in the apparent position of an object viewed along two different lines of sight, and is measured by the angle or semi-angle of inclination between those two lines. Distance between the two viewpoints is called\xa0Basis.Measuring distance of a planet using parallax methodSimilarly, α = d/DWhereα\xa0=\xa0angular size\xa0of the planet (angle subtended by d at earth) and\xa0d\xa0is the\xa0diameter\xa0of the planet.αis angle between the direction of the telescope when two diametrically opposite points of the planet are viewed.
