Its story

40 Leonis is, in cosmic terms, surprisingly close: only 69.7 light-years away. A yellow-white star of the Delta Scuti family, it is slightly hotter and nearly five times more luminous than the Sun, and pulses on hours-long periods just below visibility. A common-proper-motion companion drifts beside it more than five thousand arcseconds away; together they have shared the same journey through the Galaxy for over two billion years.
