Ball of Light, back & forth, went out of site w a bright blue/purple color, couldn't take my eyes off it.

Baltimore Maryland, Hamilton, @ 10:40pm I went outside to smoke a couple, looked across street up at the sky bc I noticed a low hanging star, I thought to myself, gosh, that star seems too low in the sky, as I am staring at the star, trying to discern if it's truly a start or am I seeing the street lights reflected on electric wire, the ball of light (no bigger than the star) started moving to right (above the houses & tree-line), its movement was quick, no noise, & it would disappear slightly as it went through the clouds (I could still make out the clouds across the sky above my house @ that time). The ball of light moved quickly to the right, stayed still a few milliseconds, then went to the left back towards this "low hanging star" I was originally looking at, & before it went out of my sight the ball of light looked aqua/blue/purple almost, before it disappeared from my sight. It was so beautiful I couldn't take my eyes off it as it moved effortlessly across the sky, and I was thinking to myself, "am I really seeing this? "
