Phys.org / 3 billion-year-old white dwarf still consuming its planetary system challenges previous assumptions

In approximately 5 billion years, the sun will deplete its hydrogen fuel and collapse under its own gravity, becoming a white dwarf. Though Earth-sized, this dense remnant will retain much of the sun's gravitational influence.
