Venus has the hottest surface temperature among all the planets in our solar system, with an average temperature of 462 °C (863 °F).

Venus has an extremely dense and thick atmosphere, with a surface pressure 92 times that of Earth.

Venus's atmosphere is composed of 96.5% carbon dioxide, 3.5% nitrogen, and trace amounts of other gases.

Venus has the longest day of any planet in our solar system, lasting 1,461 Earth days.

Venus has the shortest year of any planet in our solar system, lasting only 225 Earth days.

Venera 3 was the first spacecraft to successfully land on Venus, doing so in 1966.

Venera 9 was the first spacecraft to successfully return images from Venus, doing so in 1975.

Magellan was the first spacecraft to successfully map the entire surface of Venus, doing so in 1990.

Akatsuki is the most recent spacecraft to visit Venus, entering orbit around the planet in 2015.

The primary goal of the Akatsuki mission is to study Venus's atmosphere, including its composition, circulation, and dynamics.

Exploring Venus is challenging due to its extreme surface temperature, dense and thick atmosphere, and high atmospheric pressure.

Scientists hope to answer a variety of scientific questions through Venus exploration, including how Venus became so hot, why it has such a thick atmosphere, and whether there is any evidence of past or present life on the planet.

Venus exploration has the potential to provide a variety of benefits, including an improved understanding of climate change, the development of new technologies for extreme environments, and inspiration for future generations of scientists and engineers.

There are a number of challenges that need to be overcome in order to successfully explore Venus, including developing spacecraft that can withstand extreme temperatures and pressures, finding ways to communicate with spacecraft through Venus's thick atmosphere, and developing methods for landing and operating spacecraft on Venus's surface.

There are several proposed Venus missions in the planning stages, including the VERITAS mission, which aims to study Venus's surface, and the DAVINCI+ mission, which aims to study Venus's atmosphere.
