The cloud of 11327 clones of the star ALS 9243 drawn according to the covariance matrix taken from the Gaia DR2 catalogue. This cloud is projected onto the maximum scatter plane X'Y', coordinates are expressed in parsecs. The red dot is the Sun position, the green dot is the star nominal position during an encounter and the orange cross is the centroid of the clone cloud. The blue dotted circle shows the approximate extend of the cometary Oort cloud. This star parameters have the poor accuracy but the star must be studied in detail since it might have a large mass, even grater than 10 solar masses. Gliese 710 will pass the Sun even closer.
