Venus has a diameter of 12,103.6 km (7,520.8 mi) ... The slightly smaller size of Venus means pressures are 24% lower in its deep interior than Earth's. [75]
It was believed that the cutoff for round objects is somewhere between 100 km and 200 km in radius if they have a large amount of ice in their makeup; [1] however, later studies revealed that icy satellites as large as Iapetus (1,470 kilometers in diameter) are not in hydrostatic equilibrium at this time, [2] and a 2019 assessment suggests that ...
12.104 Mm – diameter of Venus; 12.742 Mm – diameter of Earth; 12.900 Mm – minimum distance of the meteoroid 2004 FU 162 from the centre of Earth on 31 March 2004, closest on record; 14.000 Mm – smallest diameter of Jupiter's Great Red Spot; 19.000 Mm – separation between Pluto and Charon; 30.8568 Mm – 1 nanoparsec
The moons of the trans-Neptunian objects (other than Charon) have not been included, because they appear to follow the normal situation for TNOs rather than the moons of Saturn and Uranus, and become solid at a larger size (900–1000 km diameter, rather than 400 km as for the moons of Saturn and Uranus).
Venus is the second planet in orbit and the sixth largest planet. It's often referred to as "Earth's twin" because it's similar in size and structure to our planet, but Venus has extreme surface ...
According to data from the Pioneer Venus Orbiter altimeters, nearly 51% of the surface is located within 500 meters (1,600 feet) of the median radius of 6,052 km (3,761 mi); only 2% of the surface is located at elevations greater than 2 kilometres (1.2 mi) from the median radius.
The following outline is provided as an overview of and topical guide to Venus: . Venus – second planet from the Sun, orbiting it every 224.7 Earth days. It has the longest rotation period (243 days) of any planet in the Solar System and rotates in the opposite direction to most other planets.
Venus, our closest planetary neighbor, is sometimes called Earth's twin based on their similar size and rocky composition. While its surface is baked and barren today, might Venus once also have ...
