The cloud of 13517 clones of the star Gliese 710 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 are known with a good precision so the cloud of clones is rather compact.
