Closest approach is supposed to be .41 AU. No need for financial planners to worry about this one.
Lulin will pass 0.41 AU (Astronomical Unit) from earth and reach the closest distance to Earth on Feb. 24 about 14.5 times the distance between Earth and the Moon. One AU is the distance between Earth and the Sun.

I don’t know. That seems a little close for comfort. (especially since they don’t know how it will react as it approaches the Sun.)
