The Sun, planets, moons and dwarf planets (true color, size to scale, distances not to scale) The following outline is provided as an overview of and topical guide to the Solar System: Solar System – gravitationally bound system comprising the Sun and the objects that orbit it, either directly or indirectly. Of those objects that orbit the ...

A rogue planet (Likely a sub-brown dwarf) that is surrounded by a protoplanetary disk. It is one of youngest free-floating substellar objects with 0.5–10 Myr. GSC 06214-00210 b: 1.8 ± 0.5: 16 M J, likely brown dwarf TrES-4b: 1.799 ± 0.063: This planet has a density of 0.2 g/cm 3, about that of balsa wood, less than Jupiter's 1.3g/cm 3. WASP ...
Sizes to scale. The Earth Similarity Index ( ESI) is a proposed characterization of how similar a planetary-mass object or natural satellite is to Earth. It was designed to be a scale from zero to one, with Earth having a value of one; this is meant to simplify planet comparisons from large databases. The scale has no quantitative meaning for ...
The planet is the only one known to be in the orbit of the star MOA-2009-BLG-387L, which is an M-type dwarf star that has a mass that is approximately 0.19 times that of the Sun. The star is located at an estimated 5700 parsecs (18,591 light years ) from the Earth. [2]
Megascale engineering. Megascale engineering (or macro-engineering) [1] is a form of exploratory engineering concerned with the construction of structures on an enormous scale. [2] Typically these structures are at least 1,000 km (620 mi) in length—in other words, at least one megameter, hence the name. Such large-scale structures are termed ...
Excluded objects. 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, and assuming its existence, a 2023 study found a mass of 8.1 ± 1.7 M 🜨, inconsistent with such a small radius.
This is a list of exoplanets within the circumstellar habitable zone that are under 10 Earth masses and smaller than 2.5 Earth radii, and thus have a chance of being rocky. [3] [1] Note that inclusion on this list does not guarantee habitability, and in particular the larger planets are unlikely to have a rocky composition. [4]
