The minimum mass is estimated at about 1.13 times Earth's mass. The maximum possible mass is not known.
Sol. (Usually referred to as "the sun".)_________________________The next-closest after that is Proxima Centauri, which is 4.2 light-years away. Curiously, Proxima Centauri is not visible to the naked eye, it is a red dwarf star, and even though it is closest, it is too small and dim to be seen!
bb
The BB travels about 100 yards depending on wind, gravity and the weight of the BB.
The BB gun doesn't go anywhere it stays in your hand. The BB travels about 100 yards depending on wind, gravity and the weight of the BB.
The smallest BB is 4.5mm. As far as I know there is no 1mm BB gun.
The nearest extrasolar planet from earth is Epsilon Eridani B about 10.5 light years from Earth. However... Epsilon Eridani B has not been verified 100% and remains unconfirmed due to the heavy magnetic field associated with that star system (which interferes with radial velocity measurements). If Epsilon Eridani B is not our nearest planetary neighbor, then that honor falls to the 3 planet system detected at Gilese 876 about 15 light years from our planet.
About 100yd
So far there are no changes.
with 0.12 gram bb's it goes 550fps and 0.20gram bb's 470fps
It depends on the Model and power source.
The Marksman 20xx series of BB rifles are all rated at 300 Feet Per Second. (FPS) This will make them fairly accurate to around 30 to 40 feet after that they began to fall off. Their is no current record as to how far the BB travels.
