been dead longer, being probably chilled through and through.
From this I conclude that all bodies in the solar system had one
genesis, and were part of the same nebulous mass. But this does
not include the other systems and nebulae; for, compared with
them, our sun, as we have seen, is itself advanced and small
beside such stars as Sirius having diameters of twelve million
miles."

As they left Pallas between themselves and the sun, it became a
crescent and finally disappeared.

Two days later they sighted another asteroid exactly ahead. They
examined it closely, and concluded it must be Hilda, put down in
the astronomies as No. 153, and having almost the greatest mean
distance of any of these small bodies from the sun.

When they were so near that the disk was plainly visible to the
unaided eye, Hilda passed between them and Jupiter, eclipsing it.
To their surprise, the light was not instantly shut off, as when
the moon occults a star, but there was evident refraction.

"By George!" said Bearwarden, "here is an asteroid that HAS an
atmosphere."

There was no mistaking it. They soon discovered a small ice-cap
at one pole, and then made out oceans and continents, with
mountains, forests, rivers, and green fields. The sight lasted
but a few moments before they swept by, but they secured several
photographs, and carried a vivid impression in their minds.
Hilda appeared to be about two hundred miles in diameter.
