HD7977 - a past solar visitor?

About this image

Used Seestar to locate this 9th magnitude sun-like star which recent data from Gaia satellite suggest may have passed within 1/2 light year of the Sun 2.5 million years ago - close enough to perturb objects within Oort Cloud to produce comets at that time? Further information : Wikipedia etc.
