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.
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. Reason It's a mind-blowing sequence. The viewer is invited to reflect on stars so large their size strains the limits of comprehension.
For the giant planets, the "radius" is defined as the distance from the center at which the atmosphere reaches 1 bar of atmospheric pressure. [ 11 ] Because Sedna and 2002 MS 4 have no known moons, directly determining their mass is impossible without sending a probe (estimated to be from 1.7x10 21 to 6.1×10 21 kg for Sedna [ 12 ] ).
The eight planets of the Solar System with size to scale (up to down, left to right): Saturn, Jupiter, Uranus, Neptune (outer planets), Earth, Venus, Mars, and Mercury (inner planets) A planet is a large, rounded astronomical body that is generally required to be in orbit around a star, stellar remnant, or brown dwarf, and is not one itself.

A giant planet, sometimes referred to as a jovian planet (Jove being another name for the Roman god Jupiter), is a diverse type of planet much larger than Earth. Giant planets are usually primarily composed of low- boiling point materials ( volatiles ), rather than rock or other solid matter, but massive solid planets can also exist.
TrES-2b (also known as Kepler-1b or GSC 03549-02811b) is an extrasolar planet orbiting the star GSC 03549-02811 located 750 light years away from the Solar System.The planet was identified in 2011 as the darkest known exoplanet, reflecting less than 1% of any light that hits it.
The stars with the most confirmed planets are the Sun (the Solar System's star) and Kepler-90, with 8 confirmed planets each, followed by TRAPPIST-1 with 7 planets. The 1,033 multiplanetary systems are listed below according to the star's distance from Earth. Proxima Centauri, the closest star to the Solar System, has three planets (b, c and d).
Tiny Planets is an animated children's television series produced by Sesame Workshop, and Pepper's Ghost Productions.The concept was designed and developed by Ed Taylor. The television series consists of 65 five-minute, [3] dialogue-free (and later narrated by Kim Goody, the singer of the theme song) episodes featuring two white-furred extraterrestrials travelling their universe and solving a ...
