“If the planet has an atmosphere, it can be used for aerobraking to slow down the spacecraft, and this has been done at Mars.”

“A planet in detriment or fall is in a precarious condition, more so if it is peregrine or otherwise afflicted.”

“He stared, wide eyed, as the flames floated down to the planet below the aerial battle.”

“The planetoid, believed to be half rock and half ice, is named after the Inuit goddess said to have created the sea creatures of the Arctic.”

“Sedna, the planetoid 1,000 miles in diameter discovered several weeks ago, was first photographed with a small moon orbiting its icy sphere.”

“A NASA funded team today announced the discovery of a planetoid located a mere 8 billion miles from Earth.”

“Over 150 people, including school and college students, turned up at the planetarium on Thursday evening to view the celestial bodies.”

“After all, planetesimal sized portions of the Solar System cannot be considered to be orbiting the Earth, except in the obvious case of the Moon.”

“His greatest contribution, however, was his planetesimal hypothesis of the origin of the planets.”

“Models of planetesimal disks suggest that low relative velocities between the bodies produce accretion rather than fragmentation.”

“The Kuiper belt and Oort cloud are populations of icy planetesimals located beyond the orbit of Neptune.”

“Planet cores and terrestrial rocky planets would accrete from the planetesimals.”

“Like the hills and valleys on a contour map the gravity wells of suns, planets, moons, and planetesimals showed up.”

“I didn't know all planets and planetoids were officially supposed to be named after gods of mythology.”

“Speculation has taken place on the exploitation of the materials of planets and planetoids.”

“This shorter rotation period is typical of planetoids in our solar system, requiring no external influences to explain.”

“How many planets does Person A have in water signs, how many in earth, how many in fire and how many in air?”

“All the planets should have started warm, when gravitational energy was transformed into heat during planetary accretion.”

“They presented a guide to the movement of the planets, the phases of the Moon and even the mythology of some famous constellations.”
