How far are we from the constellation draconis?

i'd like to know or learn how to determine where philippines or quezon city will be when the star Polaris moves from the ursa minor to the constellation Draconis.How far are we from the constellation draconis?It is approximately 88 light years from Earth.How far are we from the constellation draconis?1) Constellations have no reality in space. They are merely a group of stars in the same general direction in space as seen from Earth, but at many different distances. You can say how far we are from any individual star in Draco, but not the constellation as a whole.



2) The star Polaris is not moving significantly. What is moving is the direction in which the polar axis of the Earth is pointing. Currently it is pointing at Polaris, a star in Ursa Minor. In 10,000 years or so, it will be pointing at Thuban, a star in Draco. Neither star will have moved much, but the polar axis of the Earth will have moved.



3) The change in the direction the Earth's axis is pointing will have no effect on the location of the Philippines, Quezon City, or any place on Earth. Our coordinate system of longitude and latitude is relative to the rotational pole, and does not change as the direction the pole points changes.How far are we from the constellation draconis?Constellations are composted of many unrelated stars; each star is at a different distance. Ursa minor is not moving into Draco.How far are we from the constellation draconis?
