Though it is hard to find this Blue planet Neptune from the Naked Eye, but can be traced in absence of Moonlight and from a Dark place.
You may have to make certain calculations using a Star Map because Neptune planet is far-far away from Earth. I traced the location of Neptune, as being visible tonight from India.
If you have telescopes and love star grazing, then don’t miss this opportunity. Time is ticking as Earth is revolving. 😉
