Definition of planetoid in English: planetoidnoun ˈplanɪtɔɪdˈplænəˌtɔɪd another term for asteroid Example sentencesExamples - He and his colleagues expected that the images would show two distinct objects - the planetoid and its moon.
- A NASA funded team today announced the discovery of a planetoid located a mere 8 billion miles from Earth.
- This shorter rotation period is typical of planetoids in our solar system, requiring no external influences to explain.
- Another highly notable location is the galaxy's largest spaceship dump, which may be found around the back side of the planetoid.
- In recent years astronomers have spotted several Kuiper-belt planetoids, including ones named Quaoar and Varuna; the latest has been nicknamed Santa.
- The new planetoid has been named Sedna after the Inuit goddess of the ocean, and is eight billion miles away in the furthest reaches of the solar system, three times the distance from Earth than the previously furthest known planet, Pluto.
- 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.
- But Sedna is smaller and more eccentric still, so if you count out Pluto, you have to count out Sedna too (and all the other remote planetoids discovered over the past few years).
- The discovery of a small planetoid in the Kuiper belt, the distant disk of debris whose chunks eventually formed the solar system, make Pluto's chances of holding onto its status of bona fide planet weaker.
- Sedna, the planetoid 1,000 miles in diameter discovered several weeks ago, was first photographed with a small moon orbiting its icy sphere.
- The Earth and Moon formed rather late in this process, from a collision between two large bodies - a mars-sized planetoid and a slightly larger body.
- I wanted to know more about meteorites and the clues to the deeper layers of our own planet offered by the bits that they carry from the core of shattered planetoids.
- Speculation has taken place on the exploitation of the materials of planets and planetoids.
- It orbits the sun on a highly elliptical path which, even at its perihelion, puts the planetoid more than twice the average distance from the Sun to Pluto.
- Most of these are in stable orbits around the Sun and are really just small planets, or planetoids.
- It is from these exchanges that Earth finally begins to establish colonies on other planets (and planetoids besides the moon) in order to deal with its overwhelming population.
- If Sedna did form this far out, it is likely to be accompanied by a cohort of other large planetoids in this very distant region of the solar system.
- The geosphere or rocky Earth formed from collisions of planetoids.
- I've heard a good astronomical theory that the moon was created by a planetoid crashing into the earth a long time ago, possibly carrying with it the seeds for life itself.
- I didn't know all planets and planetoids were officially supposed to be named after gods of mythology.
