The largest asteroids with an accurately measured mass, due to the fact that they have been (and are being) studied by the probe Dawn, are 1 Ceres with a mass of 939.3Â±0.5Ã10 kg, and 4 Vesta at 259.076Â±0.001Ã10 kg.
The biggest known by mass is R136a1 : see List of most massive stars. The largest known by volume is UY Scuti : see List of largest stars. R136a1 is in the nearby Large Magellanic Cloud , where it is also relatively easy to see things and be certain of their distance. UY Scuti is a mere 9,500 light-years away: our own galaxy is at least 100,000 light-years across.
