They deduced that the comet expelled about 2,000 kilograms of carbon monoxide each second, roughly the rate that Comet Halley attained in 1986 during its closest approach to the sun.
Researchers speculate that such an orbit enables the sun to heat the icy body at a more constant rate, making it less likely that the comet would explosively eject as much gas and dust as Halley during its closest approach.
Few astronomers would expect to find ice on Mercury, the planet that lies closest to the sun's warming rays.
From the initial results, it appears that two of the three blasts registered at the seismic stations closest to the explosions.
Furthermore, the Venus-orbiting Pioneer spacecraft, which in January had experienced the closest view of the comet's closest approach to the sun, had revealed that the amount of water vapor coming off of the nucleus did not vary smoothly with the changing heat input.
