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.
The longitudes of perihelion were only 29 degrees apart at J2000, so the smallest distances, which come when inferior conjunction happens near Earth's perihelion, occur when Venus is near perihelion. An example was the transit of December 6, 1882: Venus reached perihelion Jan 9, 1883, and Earth did the same on December 31.
A transit of Venus takes place when Venus passes directly between the Sun and the Earth (or any other superior planet), becoming visible against (and hence obscuring a small portion of) the solar disk. During a transit, Venus is visible as a small black circle moving across the face of the Sun. Transits of Venus reoccur periodically.
At that close distance, "Parker will cut through plumes of plasma still connected to the Sun," NASA says, adding that the probe will be "close enough to pass inside a solar eruption, like a surfer ...
Since the spacecraft launched in 2018, it has circled gradually closer to the sun – flying past Venus in order to use the planet’s gravity to move it into a tighter orbit.

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.
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 meet Venus in early March.
