How Long Does It Take To Get To The Planets In Our Solar System?

To get to the planets in our solar system, you will need fuel.
And I’m not talking about a small amount of it. The fuel is vital to send our rocket into interplanetary space, but it is also needed for maneuvers corrections and changing of orbits.
There are actually many ways to reach a target – in our case, the planets – and they are all different from each other, but one thing is sure: all of them, make use of an amazing combination of math and physics knowledge. In fact, planets are moving in space, and if you think we only need to just “aim and sht”, I’m sorry to inform you that you’re wrong.
Thankfully, we have a nice description of how planets of the solar system move in space – their motion happens in the potential of the Sun, and the orbits are almost circular. Let’s say, in general, they are elliptical orbits. This is indeed what Kepler found some centuries ago.
So, once we understand that the aim-and-sht method can’t work, we need a different approach.
We could decide, for example, to reach a planet by means of the Homman transfer.

Let’s start with Mercury. Distance from the sun:
36 million miles (58 million km). Minimum distance from Earth: 56.5 million miles (91 million kilometers).

As concerns Venus, its distance from the Sun is 79.5 million miles (128 million kilometers),
And the minimum distance from Earth is 25 million miles (41 million kilometers)
