I got a good question, and because I'm a big fan of space travel and questions astronomical, I did some research and came up with some fun answers. Hope you enjoy!
Q: How far away in Earth-time would it take a rocket (average sort of rocket speed assumed) to reach the moon? Same question for Mars, Jupiter, and the Sun?
The Moon is about 240,000 miles away. To get into Earth orbit, you need to zip along at 17,500 mph. To reach escape velocity from Earth, you must up that to about 23,000 mph. If you traveled at the speed of the Apollo astronauts - who roared atop Saturn V rockets to the Moon in the late 60s through early 70s at 23,000 to 24,000 miles per hour - it would take a little over 3 days (Apollo 11 did it in 3 days, 3 hours, 49 minutes).
But wait - 240/24 = 10 hours, right? What's up with these numbers? Why doesn't a trip to the Moon take just 10 hours? The answer lies in physics.
If you don't care about slowing down to land safely, no biggie. Go ahead and crater into the surface of the Moon 10 hours after launch - it'd be exciting for those of us here on Earth to watch! If you miss, though, you'll keep zooming along past the Moon. If you swing by closely enough, you'll even get a little added gravitational boost to scoot you fast enough to reach the outer Solar System.
This is because escape velocity from the Moon is only about 5,300 mph. Faster than that, you'll just fly by (unless you hit, of course). So, because you need to slow down for insertion into lunar orbit, you lose a lot of time. Then you need to orbit a bit to prep for landing, find a good spot, and so forth.
Now, if you poodle along at highway speeds (just play along - you're using a dark-matter drive so you can ignore escape velocities and such, okay?), it would take about 145 days. Get a co-driver, unless you plan to sleep, in which case add a few months. On the other hand, Apollo 10 holds the record for the the fastest any human has ever traveled: 24,791 mph.
To reach Mars is another matter. At its closest, Mars is 34 million miles away; at its farthest, 249 million miles. Its escape velocity is only 11,000 mph, so you'll want to decelerate a bunch once you get there. But at, say, an average velocity of 25,000 mph, you'll reach Mars in 9960 hours, or 13.6 months.
Flying to the Sun - 93,000,000 miles away (about 400 times farther away than the Moon) - wouldn't take you 400 times as long, because you wouldn't need to slow down at all. That's because the Sun's escape velocity is 1,380,000 mph. That's MILLION miles per hour. Heck, you'll even speed up as you approach this flaming mass of incandescent gas, eliminating even more travel time. Let's say it'll take about 3000 hours (a little over 4 months).
Same deal for travel to Jupiter, which has an escape velocity of 133,300 mph. Basically, just drop as deeply as you can into every planet's gravity well along the way to help get you going as fast as you can, because you'll have trouble attaining speeds higher than its escape velocity without bringing along lots of additional propellant for your fusion drive or whatever. It lies about 391,000,000 miles away at its closest, 577,000,000 miles at its farthest. So, traveling along at 30,000 mph, you'll reach Jupiter in 13,000 to 19,000 hours. Just call it at least two years.
I hope you enjoyed!

Yeah, at its closest, Mars is just a hop, skip, and jump away compared to the Sun. It regularly blows me away how much energy that star puts out!

Basic Critic Against The Physics Book
It's the main problem I found in the solar system Geometry- the Physicist sees something but the designer sees another thing– these are two different visions for the same solar system- that answers (Why Are So Many Theories In The Physics Book Just Imaginary Ideas And Not Facts?)– let's discuss this problem
The Physicist Vision
The physicist supposes that there's (a unit of building)- by that- the physicist sees the mass (for example) as wall and this wall is consisted of bricks (small similar units) and for that the physicist searched for this (unit) because it's the (unit) by which the wall is building (the mass is building)– this is the physicist thinking direction- he believed there's a small unit by which the great building is built
For that the physicist searched and found the particle and then the particle is divided into Molecules then the Molecule is divided into atoms and the atom is divided into nucleus and electron moves around and the nucleus is divided into proton and Neutron- and the proton is divided into quarks …etc
The physicist searches for the building unit- the unit by which the building is built – or the unit by which the mass is built – for that the physicist divides (any thing) to see its contents till reach to the unit which can be used as the building unit.
The Designer Vision
The designer aims to create integration- as the marriage – male and female- the relationship will cause to give birth for a child
INTEGRATION this is the word inside the designer Mind
No building unit- the marriage answers- because in marriage both (male and female) are required and no one of them better than the other – both work together and give equal effects on the same one process and give together one result- I explain the idea by the marriage because it's easy to understand- I want to put the word (Integration) as the basic concept in the designer mind
And
I want to explain how the physicist causes fatal error for the research method
While the physicist divides the elements one after one (from matter to particle to molecule to atom to proton to quarks …etc) this division from out into inner till reach to very small unit which he considered the building unit – that causes to destroy the geometrical design of the integration process
Let's return to the marriage- the marriage requires two players (male and female)- they have different bodies and the process give birth for children- Suppose we remove one player what would happen? (where can we find a woman pregnant by herself?)
I want to say- the division from (matter to particle to molecule to atom to proton to quarks …etc) destroys the general geometrical design which uses the integration process- let's give other examples
Example No. (1)
Einstein told us (He can't find slightest meaning for the word SPACE BUT
Planet moves and its motion produces energy (1/2 mv^2) and where's the energy? logically we suppose that- the energy is stored in the space in waves form (CONT)
