Earth is IN a galaxy - as is the nebula.
Orion Nebula is much further from the earth than the Sun is.
A Galaxy is far bigger than a nebula.
Yes, a galaxy is typically much larger than a nebula. Galaxies are massive systems containing billions to trillions of stars, while nebulae are clouds of gas and dust in space that can range in size from a few light-years to hundreds of light-years across.
The Helix Nebula is much larger than Earth. It spans about 2.5 light-years in diameter, while Earth's diameter is about 12,742 kilometers. This means the Helix Nebula is thousands of times larger than Earth.
Yes, much bigger. There are many stars in our galaxy, thousands of millions of them. Everything you see in the night sky is in our galaxy, including the Moon, so the galaxy is much bigger.

* Galaxy * Nebula * Star * Planet * Moon However, some moons are larger than planets, and some planets and moons are larger than some stars. A constellation is an imaginary pattern of stars, so one cannot speak of its actual size.
No, the Crab Nebula is not part of the arm of Sagittarius. It is located in the constellation Taurus and is the remnant of a supernova explosion observed in 1054 AD. The nebula is situated in the Perseus arm of the Milky Way galaxy, rather than the Sagittarius arm.
No.
No, the Milkey Way is the galaxy that Earth is in.
A galaxy is a massive, gravitationally bound system that consists of stars and stellar remnants interspersed with a medium of gas, dust, and dark matter.A nebula is an interstellar cloud of dust, hydrogen, helium and other gases.However, in some older Astronomy literature, all "fuzzy objects" were called nebula, even if they were technically galaxies. This is because scientists had not yet established that galaxies were, in fact, objects outside the Milky Way.They were presumed to be among the local gas & dust objects in our own galaxy. Edwin Hubble made the essential determination that some "nebulae" were considerably further away than other objects in the milky way and were, in fact, separate galaxies.
The Milky Way galaxy is vast, measuring about 100,000 light-years in diameter, while a typical nebula can range from a few light-years to several hundred light-years across. This means that the Milky Way is astronomically larger than individual nebulae, which are often regions of gas and dust where new stars are formed. For context, even the largest nebulae, like the Orion Nebula, are mere specks compared to the overall size of our galaxy.
