As the trend in the Earth Impact Database for about 26 confirmed craters younger than a million years old shows that almost all are less than two km (1.2 mi) in diameter (except the three km (1.9 mi) Agoudal and four km (2.5 mi) Rio Cuarto), the suggestion that two large craters, Mahuika (20 km (12 mi)) and Burckle (30 km (19 mi)), formed only ...
There are 7,408 known exoplanets, or planets outside the Solar System that orbit a star, as of January 26, 2024; only a small fraction of these are located in the vicinity of the Solar System. [2] Within 10 parsecs (32.6 light-years ), there are 106 exoplanets listed as confirmed by the NASA Exoplanet Archive .
These lists contain the Sun, the planets, dwarf planets, many of the larger small Solar System bodies (which includes the asteroids), all named natural satellites, and a number of smaller objects of historical or scientific interest, such as comets and near-Earth objects.
Gaia BH1 is 1,560 light-years away from Earth in the direction of the constellation Ophiuchus. [3] For comparison, the nearest star to the Sun (Proxima Centauri) is about 4.24 light years away, and the Milky Way galaxy is approximately 100,000 light years in diameter.

The carrier aircraft (initially a NASA B-52, now an L-1011 owned by Northrop Grumman) serves as a booster to increase payloads at reduced cost. 12,000 m (39,000 ft) is only about 4% of a low Earth orbital altitude, and the subsonic aircraft reaches only about 3% of orbital velocity, yet by delivering the launch vehicle to this speed and ...
The default Earth for most of DC's comics during the time the original DC Multiverse construct was in use, Earth-One was by far the most populated and explored, and it retained dominance over the other worlds which were merged with it (Earth-Two, Earth-Four, Earth-S, and Earth-X) during Crisis on Infinite Earths.
