Question

How long does it take to get to Venus from Earth?

Answer 1

Hint: Venus is composed of an inner iron core and a rocky mantle, which is identical to the composition of Earth. It is the second-brightest natural object after the moon, which is visible during night from the Earth. It is primarily made up of carbon dioxide and nitrogen with small percentages of other gases.

Complete answer: The three spacecraft which have ever been launched to Venus have recorded different time intervals to reach Venus.
The first spacecraft was Soviet Venera 1nwhich was launched in 1961 had recorded 97 days.
The second spacecraft was NASA’s Mariner which was launched in 1962 and recorded 110 days. It was the first successful Venus flyby. The recent one was ESA’s Venus Express. It was launched in 2005 and took 153 days. Such huge differences in travel times is due to the launch speed and trajectory. Both Earth and Venus travel on orbits around the Sun. One doesn't point spacecraft directly at Venus and fire rockets. One has to traverse on a transfer orbit that moves between the Earth’s orbit and Venus’ orbit, catching up with Venus, ideally going into orbit. To make the trip with a minor, less costly rocket, one has to make a longer trip, taking more time.

Note: -Venus is the second planet from the sun but it is the hottest. This is because it has high concentrations of carbon dioxide. This produces an intense greenhouse effect and traps more heat from the atmosphere.
-All the planets in our solar system spin in an anti-clockwise direction, except Venus. It spins in a clockwise direction.
- Venus takes 224.7 Earth days to travel around the sun.
