For the small outer irregular moons of Uranus, such as Sycorax, which were not discovered by the Voyager 2 flyby, even different NASA web pages, such as the National Space Science Data Center [6] and JPL Solar System Dynamics, [5] give somewhat contradictory size and albedo estimates depending on which research paper is being cited.
Kepler-37e is listed with a radius of 0.37 ± 0.18 R 🜨 in the Exoplanet Archive based on KOI data, but the existence of this planet is doubtful, [22] and assuming its existence, a 2023 study found a mass of 8.1 ± 1.7 M 🜨, inconsistent with such a small radius.
13 things in the gigameter group Upper part: Gamma Orionis, Algol B, the Sun (centre), and other objects to scale. The gigametre (SI symbol: Gm) is a unit of length in the metric system equal to 1 000 000 000 meters (10 9 m). To help compare different distances this section lists lengths starting at 10 9 meters (1 gigameter (Gm) or 1 billion ...
Here's what to know about the short life of what was, for a single human lifetime, the solar system's smallest planet. When was Pluto discovered? Pluto was discovered in 1930 by Clyde Tombaugh, an ...
The size of the star was obtained using asteroseismology; [7] Kepler-37 is currently the smallest star to be studied using this process. [6] This allowed the size of Kepler-37b to be determined "with extreme accuracy". [6] To date, Kepler-37b is the smallest planet discovered around a main-sequence star [b] outside the Solar System.

This was once the smallest known actively fusing star, when found in 2005, through 2013. It is the smallest eclipsing red dwarf, and smallest observationally measured diameter. [101] [102] [103] CoRoT-15b: 82,200 Brown dwarf [104] VB 10: 82,300 Red dwarf: It was the smallest known star from 1948 to 1981. [105] TRAPPIST-1: 82,925
The smallest penguin species is the little blue penguin (Eudyptula minor), which stands around 30–33 cm (12–13 in) tall and weighs 1.2–1.3 kg (2.6–2.9 lb). [74] The smallest bird of prey is the Black-thighed falconet (Microhierax fringillarius), with a wingspan of 27–32 centimetres (11–13 in), roughly the size of a sparrow. [75]
In this map of the Observable Universe, objects appear enlarged to show their shape. From left to right celestial bodies are arranged according to their proximity to the Earth. This horizontal (distance to Earth) scale is logarithmic.
