The Milky Way, sometimes called simply the Galaxy, is the galaxy in which the Solar System is located. It is a barred spiral galaxy that is part of the Local Group of galaxies. It is one of billions of galaxies in the observable universe.

It is estimated that about 5-10% of yellow dwarf stars in the Milky Way have solar systems, based on current scientific observations and data.
Approx 23 trillion trillion trillion (2.3*10^37).
Higher, as the increased star formation rate increases the population of massive stars that can lead to supernovae explosions. Starburst galaxies have a higher concentration of gas and dust, leading to more frequent and intense supernova events compared to a galaxy like the Milky Way.
An AU is the wrong measurement, that's like asking how far it is from London to New York - in millimeters. An AU is merely the average distance from the Sun to the Earth, some 50 million km. The Milky way is about 100,000 Light years in diameter - a light year is about 10 trillion kilometers (10^16km = 10,000,000,000,000,000km). Since we are on the outer edge of one of the spirals, make that 50,000 light years from the Sun to the center of the Milky Way. So if my math is right, (50,000 * 10^16 )/ (50 * 10^6) = (5 * 10^20) / (5 * 10^7) = 10^13 AU
our solar system is on a spiral on one of the milky ways many spirals. we are in the milky way galaxy which is 100 000 light years in diameter and 10 000 light years thick at the centre.
The milky way is a GALAXY where the earth and the other 10/11 planets are in.

Depends on what you define as "big" or "small"... The nearest star from our Solar System, Toliman (Alpha Centauri), is 4 light-years away. This is already an incredible distance, by our standards; each light-year has almost 10 million million kilometers. It would take our current spacecraft thousands of years to reach there. The diameter of our galaxy (the Milky Way), however, is about 100,000 light-years - about 1,000,000,000,000,000,000 km., 10 to the power 18.
10-12 billion years old.
25,000 light years (4 times smaller than the Milky Way).

lets say the Milky Way galaxy is one hundred thousand lightyears 105 in diameter (several sources use this figure).A light year is 9,5 * 1015 meters which makes about 3.2 * 1016 feetSo the Milky Way is about 3.2 * 1021 feet across3 200 000 000 000 000 000 000
Very, very small. The milky way is 100,000 lightyears in diameter and 1000 light years in thickness (approx.). A lightyear is about 10 trillion kilometres. Mercury is about 4900 kilometres in diameter. Pretty big difference.
