The distance to the Andromeda galaxy can be measured using various methods, such as parallax measurements, standard candles (e.g., Cepheid variables), and redshift. These methods help astronomers determine the distance of Andromeda from Earth with good accuracy.
Andromeda Galaxy
Edwin Hubble measured the distance to the Andromeda Galaxy using Cepheid variable stars as standard candles. By observing how the brightness of these stars changed over time, he could determine their true brightness and then calculate their distance based on their apparent brightness. This allowed him to estimate the vast distance to the Andromeda Galaxy.
The distance to the Andromeda Galaxy is estimated at 2.5 million light-years. The distinction between "near side" and "far side" is irrelevant, since the diameter of the Andromeda Galaxy is probably less than the error in the distance estimation.
The Andromeda galaxy is a separate galaxy from our Milky Way and has its own set of planets. However, due to the vast distance between our galaxies, we are currently unable to observe individual planets in the Andromeda galaxy.
Since the Andromeda Galaxy is about 2.4 million light years away, when we observe it, we are seeing it as it was 2.4 million years ago. This is because the light we see from the galaxy today has taken approximately 2.4 million years to travel from the galaxy to Earth.

Yes. The Andromeda Galaxy is the nearest spiral galaxy to our own and is the most distance object visible to the naked eye.

Just about as far as the closest star in the Andromeda Galaxy. The diameter of the Andromeda galaxy is ... well, quite huge, but still relatively small, compared to the distance between us and the Andromeda Galaxy. And I believe this diameter may still be smaller than the uncertainty in the distance estimate!

100,00 light years away.
The Andromeda Galaxy is a spiral galaxy.
The Andromeda galaxy is approximately 2.537 million light-years away from Earth. In miles, this distance is approximately 14,800,000,000,000,000,000 miles.
The Sun is the closest of the three, followed by Neptune, then Andromeda.
At a distance of about 2.5 million light years, the Andromeda galaxy(also known as NGC 224 and M31) is the nearest galaxy to the Earth apart from smaller companion galaxies such as the Magellanic Clouds. Like the Milky Way, Andromeda is a spiral galaxy.
