Venus is the second planet from the Sun.It is a terrestrial planet and is the closest in mass and size to its orbital neighbour Earth.Venus has by far the densest atmosphere of the terrestrial planets, composed mostly of carbon dioxide with a thick, global sulfuric acid cloud cover.
While Venus approaches Earth the closest, Mercury approaches Earth more often the closest of all planets. [11] That said, Venus and Earth still have the lowest gravitational potential difference between them than to any other planet, needing the lowest delta-v to transfer between them, than to any other planet from them.

First flyby past another planet, on 19 May 1961 at less than 100,000 kilometres (62,000 mi); ... observed Venus during closest pass. Space Shuttle Atlantis
Four planets — Venus, Saturn, ... Mercury can be tough to spot because it's closest to the sun. On February 28, though, it will start to peek above the horizon just after sunset, then rise to ...
As the closest planet to Earth, Venus presented an appealing interplanetary spaceflight target. [9]: 172 Every 19 months, Venus and the Earth reach relative positions in their orbits around the Sun such that a minimum of fuel is required to travel from one planet to the other via a Hohmann Transfer Orbit. These opportunities mark the best time ...
After three astronomers met in a bar in Hawaii, they decided to look that way at the closest planet to Earth: Venus. They searched for phosphine, which is three hydrogen atoms and a phosphorous atom.
A terrestrial planet, tellurian planet, telluric planet, or rocky planet, is a planet that is composed primarily of silicate, rocks or metals.Within the Solar System, the terrestrial planets accepted by the IAU are the inner planets closest to the Sun: Mercury, Venus, Earth and Mars.
The innermost planet completes three orbits for every two by its closest neighbor. It's the same for the second- and third-closest planets, and the third- and fourth-closest planets.
