Largest in size - VY Canis MajorisLargest in mass - the supermassive black hole at the centre of the Galaxy.
Largest in size? We can't know, because we can't see the other side of the galaxy; we have NO IDEA what's over there. Largest in mass? That's easy; the supermassive black hole in the center of the galaxy.
The Sun - it has both the largest mass, and the largest diameter.
The ONLY galaxy in the "local milky way" is the Milky Way itself. If you're asking what the largest galaxy in the local group is, the Andromeda Galaxy is the largest by size but the Milky Way may be slightly larger by mass. It's definitely one of those two by any reasonable criterion, though.
Its similar in shape, both are more or less disc shaped. Both have a large mass at the centre. Both have smaller bodies orbiting this mass.
Yes. Saturn is the second largest planet in the solar system in terms of both diameter and mass.
Mass Effect Galaxy happened in 2009.
No. Although the Milky Way is a relatively large galaxy it is nowhere near the largest known. Galaxies dozens of times the size and hundreds of times the mass of the Milky Way have been observed.
Brazil is the 5th largest country in the world in both land mass and population.
Australia has the largest percent of its land mass on an island, as it is both a country and a continent. Australia's entire land mass is situated on the Australian continent, which is the world's largest island.
Mass Effect Galaxy was created on 2009-06-22.
Our galaxy, the milky way, has stars much bigger than our sun. Our sun is considered one solar mass in it's size. The Milky Way has star that range from 1/2 a solar mass to 50 or 100 solar masses.
