  2. List of Solar System objects by size - Wikipedia

    en.wikipedia.org/wiki/List_of_Solar_System...

    The known densities of TNOs in this size range are remarkably low (1–1.2 g/cm 3), implying that the objects retain significant internal porosity from their formation and were never gravitationally compressed into fully solid bodies. [10]

  3. List of gravitationally rounded objects of the Solar System

    The moons of the trans-Neptunian objects (other than Charon) have not been included, because they appear to follow the normal situation for TNOs rather than the moons of Saturn and Uranus, and become solid at a larger size (900–1000 km diameter, rather than 400 km as for the moons of Saturn and Uranus).

  5. List of star extremes - Wikipedia

    en.wikipedia.org/wiki/List_of_star_extremes

    A star is a massive luminous spheroid astronomical object made of plasma that is held together by its own gravity.Stars exhibit great diversity in their properties (such as mass, volume, velocity, stage in stellar evolution, and distance from Earth) and some of the outliers are so disproportionate in comparison with the general population that they are considered extreme.

    Astronomers have long hypothesized that as a protostar grows to a size beyond 120 M ☉, something drastic must happen. [2] Although the limit can be stretched for very early Population III stars, and although the exact value is uncertain, if any stars still exist above 150–200 M ☉ they would challenge current theories of stellar evolution.

    K2-38b, also designated EPIC 204221263 b, is a massive rocky exoplanet closely orbiting a Sun-like star and is one of the densest planets ever found.Discovered in 2016 by Crossfield et al. and later characterized by Sinukoff et al., K2-38b is a rocky super-Earth about 55% larger than Earth (nearly 20,000 km wide) but about 12 times more massive (around 7.2*10^25 kg, a bit less than Uranus ...

    The sizes are listed in units of Jupiter radii (R J, 71 492 km).This list is designed to include all planets that are larger than 1.7 times the size of Jupiter.Some well-known planets that are smaller than 1.7 R J (19.055 R 🜨 or 121 536.4 km) have been included for the sake of comparison.

    Star with the highest apparent motion (i.e, proper motion) with a planet Barnard's Star b [18] Barnard's Star: 10.358 arcsec/yr [19] As Barnard's Star has the highest apparent motion in the sky, [19] this is currently an absolute record. Largest angular distance separation from its host star COCONUTS-2b: COCONUTS-2: 594 arcseconds [20]
