Exploring Venus
The Soviet Venera spacecraft returned the first-ever images from the surface of Venus
A total of 38 spacecraft have at least partially successfully completed a mission at Venus. About a dozen or so more have
tried and failed to study this scorching hot world.
The first successful flyby of Venus was performed by NASA’s Mariner 2 spacecraft on 14 December 1962, following failed
attempts by both the Soviet Union and the USA. The first successful landing was the Soviet Venera 4 lander, which
touched down on the surface on 18 October 1967. This was followed by a number of other spacecraft in the Soviet Venus
exploration programme, culminating in two balloons known as Vega 1 and 2 in June 1985 that flew in the Venusian
atmosphere.
The most recent spacecraft to visit the planet is ESA’s Venus Express, which has been in orbit around Venus since 11 April
2006 performing scientific analysis and is expected to last until at least December 2014.
Venus’s highest average temperature is
477 degrees Celsius.
Venus’s lowest average temperature is
462 degrees Celsius.
Yes. The atmosphere of Venus is
made up mainly of carbon
dioxide, and thick clouds of
sulfuric acid completely cover the
planet.
Venus has zero moons.
All planets were named after
roman’s and Greek gods
except for earth.
0.718 astronomical units.
It takes 224.7 days and zero
years. Compare this to earth
which takes 365.25 days to
orbit the Sun.
It takes 1 year, 243 days and
zero hours.
Venus’s diameter is 7,520.8,
and it’s mass is 4.867E+24,
and it’s density is 5.24 g/cm³.
In ancient times, Venus was often thought to be
two different stars, the evening star and the
morning star — that is, the ones that first
appeared at sunset and sunrise. In Latin, they
were respectively known as Vesper and Lucifer. In
Christian times, Lucifer, or "light-bringer," became
known as the name of Satan before his fall.
