A group of impact modelers argued at the Lunar and Planetary Science Conference that the object that crashed into asteroid Vesta — the asteroid belt's second - most - massive body — and reshaped its geology was eight times as massive as previously thought.

That once - rejected work has now inspired two teams of planetary scientists to model what might have happened if an object roughly 10 times as massive as Ceres, the largest asteroid, smashed into ancient Mars.

Now, planetary scientists have conducted the first computer simulations that bolster a controversial alternative idea: The satellites formed as our own moon did, after a big object smashed into the planet and kicked up debris.

The final stages of life for a star like our Sun result in the star blowing its outer layers out into the surrounding space, forming objects known as planetary nebulae in a wide range of beautiful and striking shapes.

The stellar corpses — highly dense objects known as white dwarfs — were spotted inside a dense cloud of gas and dust known as a planetary nebula.

WASP - 39b likely had an interesting evolutionary history as it migrated in, taking an epic journey across its planetary system and perhaps obliterating planetary objects in its path.»

We conclude that the planetary scenario is more likely than that of an astrophysical false positive by a factor of 2e5 (Kepler - 20b), 1e5 (Kepler - 20c), and 1.1 e3 (Kepler - 20d), sufficient to validate these objects as planetary companions.

For most of the candidates (85 %), the transit depths measured with Kepler are consistent with the depths measured with Spitzer as expected for planetary objects, while we find that the most discrepant measurements are due to the presence of unresolved stars that dilute the photometry.

This falloff is known as the «Kuiper cliff,» and its cause is unknown, though Alan Stern of the Southwest Research Institute has claimed that a large planetary object might be responsible.

Now researchers claim that weirdly wobbling objects in the Kuiper Belt indicate the presence of yet another so - far - undiscovered planetary body at least as large as Mars.

However, many others argue that only planemos that directly orbit stars should qualify as planets, preferring to use the terms «planetary body,» «planetary mass object» or «planemo» for similar free - floating objects (as well as planet - size moons).

This planetary nebula is certainly the most impressive object of its kind in the sky, as the angular diameter of the luminous body is nearly 6 arc minutes, with a faint halo extensing out to over 15», half the apparent diameter of the Moon (Millikan 1974).

Occasionally these objects look something like planetary nebulae, as in the case of the Crab Nebula, but they differ from the latter in three ways: (1) the total mass of their gas (they involve a larger mass, essentially all the mass of the exploding star), (2) their kinematics (they are expanding with higher velocities), and (3) their lifetimes (they last for a shorter time as visible nebulae).

KAMUELA, Hawaii — With data collected from the mighty W. M. Keck Observatory, California Institute of Technology (Caltech) astronomer Mike Brown — known as the Pluto killer for discovering a Kuiper - belt object that led to the demotion of Pluto from planetary status — and Kevin Hand from the Jet Propulsion Laboratory (JPL) have found the strongest evidence yet that salty water from the vast liquid ocean beneath Europa's frozen exterior actually makes its way to the surface.

This allows it to study a variety of astronomical objects, such as the molecular gas in planetary nebulae, molecules on active comets, the heating mechanisms of red giants and the afterglows of gamma - ray bursts.

In order to be recognized as such, an object must orbit the Sun but can not be a satellite (like a moon), must have enough mass to be spherical, and has not cleared its planetary neighborhood of debris.

These comets are observed to come into the Solar System from all directions, which implies an immense spherical cloud of trillions of small icy, planetary objects — all potentially active but currently dormant comets — that extend as much as two light - years outward from Sol.

In this astronomy science project, you will model comets of different sizes and then use a hair dryer as a heat source (to mimic the Sun and other «warm» planetary objects) to determine how the size of a comet affects melting.

«These objects need to be considered as potential reservoirs of water and life,» lead author Prabal Saxena, a planetary scientist at NASA's Goddard Space Flight Center, said in a press release.

Both objects formed among the rocky and icy protoplanets beyond the Solar System's «ice line» now located around 2.7 AUs, but the early development of Jupiter apparently prevented such large protoplanets between the gas giant and planet Mars from agglomerating into even bigger planetary bodies, by sweeping many into pulverizing collisions as well as slinging them into the Sun or Oort Cloud, or even beyond Sol's gravitational reach altogether.

Potential super-Earths — all with estimated diameters (or radii) between 1.5 and 2.2 that of Earth's but with close - orbiting periods of less than 41 days — that were found and released by the Kepler Mission as part of its 306 stars with planetary candidates are listed in the table below by designation number as a «Kepler Object of Interest» (KOI).

In the description of the DE200 planetary ephemeris, it is pointed out that, contrary to all the other objects in the computation which use the Solar system barycentre, the orbit of our own moon is computed relative to the Earth - Moon barycentre, because then, the orbit integration will behave nicer numerically — which is good, as the Moon is an object of special interest.
