Ross 154 is a star about 9.68 light years from the Solar System.
9.68 light years
It varies with each planet's position in its orbit. Mars is farther out from the Sun, and orbits more slowly than the Earth does. At the "conjunction", when the two planets are closest together, they are about .5 AU apart. But 8 months later, when Earth has raced ahead and is now on the opposite side of the Sun from Mars, the distance is about 1.5 AU.
1 Astronomical Unit (1.00 AU) is the mean distance between Earth and the sun. 1 AU is approximately equal to 149,600,000 km Saturn's mean distance from the sun is 9.529 AU Saturn's maximum distance from the sun is 10.044 AU Saturn's minimum distance from the sun is 9.014 AU

Jupiter does not have a solid surface upon which to stand - just many turbulent and increasingly dense layers of gas and liquid - though it may have a very dense, solid core.However, if you were to stand where the gassy layers give way to liquid (its approximate surface), gravity would be about 25m/s2. That's over two and a half times the gravity on the surface of Earth.If you weighed 100lbs on Earth (where gravity is 9.8 m/s2), you would weigh about 254lbs on Jupiter, or be around 254% as heavy (or 154% heavier).This is because, though Jupiter is 318 times the mass of the Earth, it is 11 times greater in diameter. Gravity increases with mass, but decreases with the distance from the centre of mass. The gravitational force is g=m/r2 (gravitational constant x mass of Jupiter x mass of the object, all divided by the distance between the centres of mass squared).If you could compress the mass of Jupiter down to the size of Earth and attempt to land upon its surface, you would be crushed into oblivion - your weight would be more than 300 times as great as on Earth!The same thing it is on Earth or anywhere else in the universe . . . the characteristicof space-time that causes forces of attraction between every two masses.Gravity on Jupiter is much greater than on Earth because Jupiter is a larger planet, and therefore has much more gravitational pull. Therefore, if you weighed 100 pounds on the Earth, on Jupiter, you would weigh 236.4 pounds. But also the gravitational pull does not count on the size of a planet. While Jupiter is much larger than the Earth, it has a little more than two times the Earth's mass. Saturn, if submerged in water, will actually float because it is less dense than water.

Trivially the Sun. If you meant other than the Sun, the closest stars are the three in the Alpha Centauri system, about 4.3 light years away. One member of the system... Alpha Centauri C, aka Proxima Centauri, can get closer than the other two; at minimum it's about 4.2 light years away. It's considered at least possible by some astronomers that the sun has a dim red or brown dwarf companion at a distance of 0.1 to 1 light year. If it exists, this star has a name: Nemesis. Despite its nearness, it would not be particularly bright and would not have an especially large proper motion, so it would be difficult to identify, though if it exists it's undoubtedly been photographed many times.

A "constellation" is better thought of as a direction away from the earth, not a physical object with a particular distance. Saggitarius's nearest star is Ross 154 at 10 light-years. It is too faint to be seen with the naked eye. Saggitarius is also the direction of the core of the Milky Way galaxy, about 27 thousand light-years distant.
The average distance is: 154 miles or 247 kilometers
