As part of the huge protoplanet, the cylinder had not been disproportionate.

Because of this, some scientists refer to Vesta as a protoplanet.

This results in the inward migration of the protoplanet.

There is also no exact dividing line between a planetesimal and protoplanet.

This has led scientists to consider Vesta a protoplanet.

The reward will be the capability to scrutinize this fascinating protoplanet further.

The asteroid 21 Lutetia has also shown characteristics that resemble a protoplanet.

The core, indeed, was probably molten even at its protoplanet stage, and this formed an intensive magnetic field.

The gap in the disk leads to the conclusion of a protoplanet in formation around the star.

It was a tiny blip, settling down feather-light toward the surface of the snowball protoplanet.

If the collision happened within the last few thousand years, there is likely a protoplanet in the HD172555 system with a liquid magma surface.

Now he was stuck here, as trapped as any pre-spaceflight Neanderthal, on a protoplanet in the middle of, quite literally, nothing.

Ceres is probably a surviving protoplanet (planetary embryo), which formed 4.57 billion years ago in the asteroid belt.

He cut in maximum magnification on the screens, and the surface of the little protoplanet of frozen gases leaped up toward him.

Astronomers make the first direct observation of a protoplanet forming in a disk of gas and dust around a distant star.

Ceres (2.77 AU) is the largest asteroid, a protoplanet, and a dwarf planet.

Vesta is the last remaining rocky protoplanet (with a differentiated interior) of the kind that formed the terrestrial planets.

We have seen before that the distribution of mass inside the protoplanet reveals itself through the changing strength of its gravitational tug on Dawn.

If an eroded gas giant, the sun would have boiled the planet from a larger protoplanet, of 20 Earth masses up to half Jupiter's mass.

Swiss scientists claim that Earth's Moon may have been formed in a glancing "hit and run" collision with a large, fast-moving protoplanet.

Pallas is believed to have undergone at least some degree of thermal alteration and partial differentiation, which suggests that it was a protoplanet.

Another possible protoplanet, Vesta, is less than half the size of Ceres; it suffered a major impact after solidifying, losing 1% of its mass.

The phrase refers to an orbiting body (a planet or protoplanet) "sweeping out" its orbital region over time, by gravitationally interacting with smaller bodies nearby.

This has led to the giant impact hypothesis: the idea that the Moon was formed during a giant impact of the proto-Earth with another protoplanet.

Celebrating its anniversary of leaving Earth, Dawn is in orbit around a kindred terrestrial-type world, the ancient protoplanet Vesta.
