Parts-per-million chart of the relative mass distribution of the Solar System, each cubelet denoting 2 × 10 24 kg. This article includes a list of the most massive known objects of the Solar System and partial lists of smaller objects by observed mean radius. These lists can be sorted according to an object's radius and mass and, for the most ...
Vesta and Pallas are nonetheless sometimes considered small terrestrial planets anyway by sources preferring a geophysical definition, because they do share similarities to the rocky planets of the inner solar system. [56] The fourth-largest asteroid, Hygiea (radius 216.5 ± 4 km), is icy.
Bolometrically most luminous galaxy in the local universe and also the nearest billion-solar-mass black hole to Earth. Markarian 501: 9 × 10 8 – 3.4 × 10 9 [78] Brightest object in the sky in very high energy gamma rays.

Jupiter is the biggest planet in our solar system, according to NASA. Jupiter’s radius is over 11 times the equatorial radius of the Earth.

Verona Rupes is the tallest known cliff on Miranda, a moon of Uranus, and plausibly holds the record for the highest cliff in the Solar System.It was discovered by the Voyager 2 space probe in January 1986.
Despite being the only moon in the Solar System with a substantial magnetic field, it is the largest Solar System object without a substantial atmosphere. Like Saturn's largest moon Titan, it is larger than the planet Mercury, but has somewhat less surface gravity than Mercury, Io, or the Moon due to its lower density compared to the three. [18]
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.
