HD 98618
HD 98618 is a star 126 light years from Earth that is almost identical in most respects to the Sun; it has therefore been proposed as a candidate solar twin. However, like the solar twin 18 Scorpii, HD 98618 has a lithium abundance significantly higher than that of the Sun (() = +0.45 ± 0.08). Meléndez & Ramírez (2007) have suggested that HD 98618 be considered a "quasi solar twin", since they have now identified a solar twin, HIP 56948, with lithium content identical within the observational error to the Sun's. ==References== 〔
