Mars is at its closest to earth: 54.6 million km
The top speed of the shuttle is: 27.870 km per hours
So: around 82 days
But that sounds quite difficult, then you still have to get back, have enough fuel (which weighs you down). On space sites, you'll find different data, from 6 months to 5 years but I just calculated under the ideal circumstance's: Smallest distance, top speed.
Well apart from the fact that the shuttle couldn't or isn't even capable of going so far.
..and it would also depend on when you launched the Shuttle, depending on acceleration, deceleration and the position of the planets at the time - assuming you wanted a planetary acceleration as well.
The average distance from the Earth to Neptune is about 4,564 million km and the shuttle at top speed is about 27,870 km/h so forgetting about minor details of acceleration etc, and planets positions, in a straight line, you would reach Neptune in about 18.7 years.
First, there are no more space shuttles.
Second, no space shuttle ever got higher than about 400 miles from the Earth; it would have been impossible for a Shuttle to ever leave Earth orbit and to go anywhere else. It couldn't carry any more fuel.
Third, if you had a magically infinite supply of fuel, a Space Shuttle could have made it to Jupiter in only a few years - but you would have run out of oxygen in about 3 weeks.
It would literally take for ever to get from Earth to Uranus using the Space Shuttle. That vehicle is incapable of making the trip, and even if it were, it could not sustain live long enough for you to get there, let alone return.
10-13 years
Voyager 2 made it there in 12 years.
Assuming you could fly in a straight line at the shuttles orbital speed of 17,600 mph it would take about little less than 2 and a half years to get to Europa.
2and a half months
How long it takes a spacecraft to reach Mars depends on the changing distances between Mars and Earth as they orbit the sun, and other factors. Trips are usually planned for when Mars will be closest to Earth; the shortest is about three months. None of NASA's Space Shuttle fleet are capable of making the trip, and the remaining shuttles are due to be retired.

The Space Shuttle is not capable of going to the moon.
long time compare to earth
the shuttle does not go to the moon.

It could not, the shuttle cannot leave low earth orbit

Sally Ride never went to Mars. Nobody has. Sally Ride was an astronaut on the Space Shuttle, which is designed for low Earth orbit.
The Space Shuttle is not capable of going to the moon.
long time compare to earth
Assuming that the maximum speed of a Space Shuttle is 17,500 miles per hour, it would take about 24 days.
the shuttle does not go to the moon.
About an hour and a half.
NASA's space shuttles were not designed for long space missions; the initial idea was to build shuttles to reach the Moon. The present-day space shuttle can only reach low Earth orbit. The aging shuttle fleet (approaching thirty years old) is due to be retired. The Orion spacecraft will carry the next major American space missions.
It takes the Shuttle about 2 days to reach the International Space Station.
It would depend how fast you were traveling, but with a space shuttle it would take about a week
