The listed objects currently include most objects in the asteroid belt and moons of the giant planets in this size range, but many newly discovered objects in the outer Solar System are missing, such as those included in the following reference. [58]
Edit 1 Original - An illustration of the comparative sizes of planets and stars. Starting with the planet Mercury at the top left we follow a growing sequence of planets and then a growing sequence of stars until we reach the second largest known star VV Cephei in the bottom right. It's a mind-blowing sequence. The viewer is invited to reflect ...

The following well-known stars are listed for the purpose of comparison. Antares (α Scorpii A) 680 [66] AD Fourteenth brightest star in the night sky. [67] Widely recognised as being among the largest known stars. [19] Betelgeuse (α Orionis) 640, [68] 764 +116 −62, [69] 782 ± 55 [70] AD & SEIS Tenth brightest star in the night sky. [67]
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.
Some of these planets orbit multiple stars at the same time. Certain planets are so close to their star that it takes only a handful of days to make one revolution, compared to the Earth which ...
Comparison of the habitable zones of the Solar System and TRAPPIST-1, an ultracool red dwarf star known to have seven terrestrial planets in stable orbits around the star. Comparison of the habitable zones for different stellar temperatures, with a sample of known exoplanets plus the Earth, Mars, and Venus.
A visual size comparison of the largest known stars and planets can be explored, and real time animations of events like the Apophis asteroid passing near Earth in the year 2029 can be watched. Comets can be observed colliding into planets, such as the Shoemaker Levy 9's collision with Jupiter.
