WebFor instance: The Milky Way's visible disk has a diameter of 30 kpc. The distance to the Large Magellenic Cloud (LMC) is about 50 - 60 kpc, no more than 2x the diameter of the Milky Way. (The LMC is only 7 kpc in diameter.) The distance to the Andromeda Galaxy is 770 kpc, only about 20x the diameter of the Milky Way. WebThe Milky Way is a spiral galaxy in which most of recorded history takes place. The name "The Milky Way" comes from Earth; the galaxy is also known as the "home galaxy" to many races. The Milky Way is approximately thirteen billion years old and 100,000 light-years across, 15,000 light-years deep at the galactic core and contains approximately 200 …

WebBecause of dust, astronomers can see only about 6 kpc into the disk of the galaxy. What percentage of the galactic disk area does that include? Take the radius of the galaxy to the far outer edge to be 12.5 kpc. (Hint: consider the area of the entire circular disk and the circular area visible from Earth.) WebFor each of the following distances, if a galaxy the size of the Milky Way (about 30.1 kpc in diameter) were at that distance from the Milky Way, what would its angular size appear to be? a. 12.7 Mpc α = _____ arc minutes b. 1027 Mpc α = ______arc minutes Expert Answer Web1.Our galaxy, the Milky Way, has a steeply rising rotational velocity near the center but quickly attens out to 235 km/s. The bulge of the Milky Way has a radius of 2 kpc and a mass of 20 billion solar masses. Assuming constant mass density in the bulge, entirely made of baryonic matter, what is the maximum fitting of cardiac pacemaker icd-10-cm code
