What is the hardest planet to see?

Answer 1

Of the 8 planets (& 3 dwarf planets of which we know) in our own solar system, the most difficult one to live on would be Venus. Although any planet other than the Earth would be difficult to live on, and would require considerable technological support.

Answer 2

In our solar system, Jupiter has the highest escape velocity at around 60 km/s due to is great mass, compared to Earth which is about 11 km/s. Note that it would actually be harder to escape the solar system from Mercury because of its proximity to the mass of the Sun.

Answer 3

Neptune is the most distant planet in our solar system. It would be possible to argue that Venus, with its very high surface temperature and corrosive atmosphere, is more difficult to visit, even though it is a lot closer. Anything that visits Venus does not survive for long.

However, if we look beyond our solar system there may be a number of contenders as most difficult planets to visit from earth.

For example, shrouded in clouds of iron atoms, having a surface temperature of 3,100 degrees Fahrenheit, and being some 5,000 light years away, planet OGLE-TR-56b is a good candidate for the title "Most Difficult Planet to Visit From Earth".

Slightly larger than Jupiter, but situated in the arm of the Sagittarius constellation, planet OGLE-TR-56b, described as a world of iron rain, orbits its star, OGLE-TR-56, once every 29 days. That's fast!

However, in addition to its totally inhospitable climate, this planet's sheer distance from earth is a major challenge for potential visitors from earth.

Light travels at 186,282 miles per second. So, if we could travel at 670,615,200 miles per hour (186,282 x 60 x 60), it would take us 5,000 years to get there! And by the time we arrive... it might not even be there anymore!

n.b. As our knowledge of the universe expands, doubtless other planets even more distant and difficult to visit will be found. So please use the space below to add the names of other planets that may also qualify as being among the 'Most Difficult To Visit From Earth'

Answer 4

Neptune, because it is so far away.

Mercury is hard to see for a different reason. It is always close to the Sun in

the sky.

Answer 5

Venus, because it has clouds that rain acid and super hot temperatures!

Answer 6

Earth

Answer 7

mercury
