Relative masses of the Solar planets. Jupiter at 71% of the total and Saturn at 21% dominate the system. Relative masses of the solid bodies of the Solar System. Earth at 48% and Venus at 39% dominate. Bodies less massive than Pluto are not visible at this scale. Relative masses of the rounded moons of the Solar System.
Notes Size limit for brown dwarfs: 8 [1] Proplyd 133-353 7.82 ± 0.81 R J (0.804 ± 0.083 R ☉) [2] [a] A candidate rogue planet/sub-brown dwarf with a photoevaporating disk. It is located in the Orion Nebula Cluster. At an age younger than 500,000 years it is one of the youngest free-floating planet candidate known.
The number of dwarf planets in the Solar System is unknown. Estimates have run as high as 200 in the Kuiper belt [1] and over 10,000 in the region beyond. [2] However, consideration of the surprisingly low densities of many large trans-Neptunian objects, as well as spectroscopic analysis of their surfaces, suggests that the number of dwarf planets may be much lower, perhaps only nine among ...
Jupiter is the biggest planet in our solar system, according to NASA. The planet is what’s known as a gas giant, which means it doesn’t have a solid surface — though it may have a solid core ...
The mean apparent magnitude is 0.23 while the standard deviation of 1.78 is the largest of any planet. The mean apparent magnitude at superior conjunction is −1.89 while that at inferior conjunction is +5.93. [16] Observation of Mercury is complicated by its proximity to the Sun, as it is lost in the Sun's glare for much of the time.
720,000 km/h (450,000 mi/h) [ 10] Orbital period. ~230 million years [ 10] The Solar System[ d] is the gravitationally bound system of the Sun and the objects that orbit it. [ 11] It was formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc.
The Chinese municipality of Chongqing, which is the largest city proper in the world by population, comprises a huge administrative area of 82,403 km 2, around the size of Austria. However, more than 70% of its 30-million population are agricultural workers living in a rural setting. [6] [7]
List of countries by population (United Nations) This is a list of countries and other inhabited territories of the world by total population, based on estimates published by the United Nations in the 2024 revision of World Population Prospects. It presents population estimates from 1950 to the present. [ 2]
