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.

Right now, Venus is this blazing bright dot like an airplane,” he said. Planetary parades occur because the planets orbit the sun on a relatively flat, disk-shaped plane.
During the probe's Dec. 24 close approach, known as perihelion, NASA mission control will be unable to contact Parker for some three days. If successful, the probe will send a beacon tone to the ...
The orbit of Venus has an inclination of 3.39° relative to that of the Earth, and so passes under (or over) the Sun when viewed from the Earth. [1] A transit occurs when Venus reaches conjunction with the Sun whilst also passing through the Earth's orbital plane, and passes directly across the face of the Sun. [citation needed] [note 1 ...
LOS ANGELES (Reuters) -NASA on Wednesday announced plans to launch two new scientific missions to Venus between 2028 and 2030 - its first in decades - to study the atmosphere and geologic history ...
In 2007, the Venus Express mission confirmed the presence of lightning on Venus, finding that it is more common on Venus than it is on Earth. [52] [53] MESSENGER passed by Venus twice on its way to Mercury. The first time, it flew by on October 24, 2006, passing 3000 km from Venus. As Earth was on the other side of the Sun, no data was recorded ...
