Which of the following information for "Local Group" is incorrect?The recommended time to answer this question is 2.5 minutes.Soru 13YanıtIt is the group of galaxies in which the Milky Way Galaxy is located.It is known that more than 50 galaxies are members of the group.Most of the member galaxies of the group are dwarf elliptical or irregular galaxies.The most massive member of the group is the Andromeda galaxy.Small and Large Magellanic clouds, which are members of the group, are satellite galaxies of the Triangulum Galaxy.

Recall which of the following is made up of the Milky Way, the Andromeda galaxy and a few smaller galaxies. The Interstellar NeighbourhoodThe Local GroupThe Virgo SuperclusterThe universe

Which of the following information on the populations in the Milky Way Galaxy is incorrect?The recommended time to answer this question is 2.5 minutes.Soru 5YanıtPopulation I stars contain the remnants of Population II stars that have died.Population I stars are found in disc and open clusters, while Population II stars are found in halo, bulge, and globular clusters.Population I stars are younger than Population II stars.Population I stars are poorer in metals than Population II stars.The orbits around the galactic center of the Population I stars are circular, while those of the Population II stars are elliptical.
