how long does it take to get from earth to each planet?

When we send spacecraft to planets or other objects (asteroid or comet), the spacecraft is actually put into an orbit around the Sun in order to bring it close to the target planet. But, you have to deal with the gravity of the Sun. Here are some numbers: Mars - 7 months, Venus - 5 months, and Mercury - 5 months.

We see a planet like Jupiter because its light—which like the other planets and the Moon originates on the Sun—takes about 43 minutes to reach Jupiter. The return trip to the Earth can take from 35 to 52 minutes, depending on whether we are on the same side of the Sun as Jupiter or on the other side.

Mercury—1,408 hours; Venus—5,832 hours; Earth—24 hours; Mars—25 hours; Jupiter—10 hours; Saturn—11 hours; Uranus—17 hours; and Neptune—16 hours.

The total journey time from Earth to Mars takes between 150-300 days depending on the speed of the launch, the alignment of Earth and Mars, and the length of the journey the spacecraft takes to reach its target.

The actual flight time to circumnavigate the planet is about 40 hours. With 196 countries stretched around the planet's 47,000 kilometres girth, it would take several lifetimes to see it all!

The route can be as long as 885 miles, or 1424 kilometers. On average, the journey takes 36 hours and 40 minutes.

Therefore, the amount of time it would take to get to Jupiter really depends on how fast you are going, the path you take in space, and where the planets are located in their orbits. Travel to Jupiter can be anywhere between just over 13 months to eight years.

There's also fuel problem too. The shortest distance between Earth and space is about 62 miles (100 kilometers) straight up, which by general accord is where the planet's boundary ends and suborbital space begins.

It takes 8.3 minutes for light to travel from the Sun to the Earth (a distance of 1.58 × 10-5 light-years).

Mariner 10 took 147 days to get from Earth to Mercury. More recently, NASA's MESSENGER spacecraft launched on August 3, 2004 to study Mercury in orbit. It made its first flyby on January 14th, 2008. That's a total of 1,260 days to get from Earth to Mercury.

Of the people who have successfully circumnavigated the continent, it took a range of 365–897 days to complete. Distances involved are in the vicinity of 14,300 km (8,900 mi) to 17,000 km depending on the route taken.

So if we could travel at the speed of light, it would take 736 years to get there, but at our current fastest rate of space travel, it would take around 18,000 years for each light year, so it would take around 13 million years to reach the nearest star of Orion's Belt.

If you were to reach Mars based on the current speeds of spaceships, it would take roughly nine months, according to the Nasa Goddard Space Flight Centre's website. Unmanned spacecraft travelling to Mars have taken anywhere from 128 days to 333 days to reach the red planet.
1405625
The Sun is at an average distance of about 93,000,000 miles (150 million kilometers) away from Earth. It is so far away that light from the Sun, traveling at a speed of 186,000 miles (300,000 kilometers) per second, takes about 8 minutes to reach us.
422180
It is traveling away from the Sun at a rate of 17.3 km/s. If Voyager were to travel to Proxima Centauri, at this rate, it would take over 73,000 years to arrive. If we could travel at the speed of light, an impossibility due to Special Relativity, it would still take 4.22 years to arrive!

How long does it take to travel to the Moon? It takes about 3 days for a spacecraft to reach the Moon. During that time a spacecraft travels at least 240,000 miles (386,400 kilometers) which is the distance between Earth and the Moon. The specific distance depends on the specific path chosen.

In fact: If you could walk from Earth to Mars at a brisk rate (about five miles per hour) it would take about 4,000 years to reach the Red Planet. If you drove a car 70 mph, it would take 228 years. If you had a 747 airlane, it would still take 32 years.
