In 2013, astronomers using the Kepler space telescope's data estimated that about one-fifth of G-type and K-type stars (sun-like stars and orange dwarfs) are expected to have an Earth-sized or super-Earth-sized planet (1–2 Earths wide) close to an Earth-like orbit (0.25–4 F 🜨), yielding about 8.8 billion of them for the entire Milky Way ...
Interacting galaxies ( colliding galaxies) are galaxies whose gravitational fields result in a disturbance of one another. An example of a minor interaction is a satellite galaxy disturbing the primary galaxy's spiral arms. An example of a major interaction is a galactic collision, which may lead to a galaxy merger .
List of nearest galaxies. This is a list of known galaxies within 3.8 megaparsecs (12.4 million light-years) of the Solar System, in ascending order of heliocentric distance, or the distance to the Sun. This encompasses about 50 major Local Group galaxies, and some that are members of neighboring galaxy groups, the M81 Group and the Centaurus A ...
By comparison, the total mass of all the stars in the Milky Way is estimated to be between 4.6 × 10 10 M ☉ and 6.43 × 10 10 M ☉. [133] In addition to the stars, there is also interstellar gas, comprising 90% hydrogen and 10% helium by mass, [139] [ unreliable source? ] with two thirds of the hydrogen found in the atomic form and the ...

The last 2-8-8-2 was retired in 1962 from the N&W's roster, two years past the ending of steam though steam was still used on steel mill lines and other railroads until 1983. A similar wheel arrangemement exists for Garratt locomotives, but is referred to as 2-8-0+0-8-2 ...
