In general, it's safe to assume that traveling shorter distances in outer space is, and will continue being, faster than traveling larger distances.The distances between planets within our own Solar System are in the order of light-minutes to light-hours, i.e., it will take light minutes or hours to go from one planet to another.
The distances to the closest stars (other than the Sun) are in the order of a few light-years. For example, the closest star (other than the Sun) is at a distance of about 4.2 light-years.
The distances between nearby galaxies are in the order of hundreds of thousands to millions of light-years.
Within a solar system.
Planet Solar System Galaxy Universe
biggest to smallest : universe, galaxy, star/solar system, planet, moon. The Universe is everything that exists and a galaxy is a cluster of billions of stars and then planets rotate around stars and moons rotate around planets.
Starting from least to greatest magnitude in size: Earth Sun Solar System Milky Way Galaxy Universe
Mars is the 4th planet from the sun in our solar system which is in the Milk Way galaxy which is part of the galaxy cluster known as the Local Group.
You would go as fast as you could, which at the moment is round about 20 miles per second for spacecraft. At that speed you would get to the nearest star in 38,000 years.

Universe, Cluster, Galaxy, Star, Planet NB: Some stars are smaller than planets.
They are in all three. Planets are in solar systems. There are lots of solar systems in a galaxy. There are lots of galaxies in the universe. So any planet is in a solar system, a galaxy and the universe.
I forgot her name but she is from a planet outside our galaxy.
The Universe is the largest body in the...well, the Universe. It never stops expanding. The Universe is full of billions of galaxies, which range in shape and size. However, none are even close to being compared in size to the Universe.

Impossible to know because we don't know EVERY galaxy. The portion of the universe that we have to ability to see is extremely small compared to the entire universe.
