asteroidal การใช้

• A graph is AT-free if it has no asteroidal triple.
• The asteroidal materials that provide meteorite samples were long known to be from the early solar system.
• This has caused renewed interest in suggestions that Earth's water may be partly of asteroidal origin.
• The spectra are distinct from those of all classes of chondrite meteorites, again pointing away from an asteroidal origin.
• If an object is originally found asteroidal, and later develops a cometary tail, it retains its asteroidal designation.
• If an object is originally found asteroidal, and later develops a cometary tail, it retains its asteroidal designation.
• The former enhancement is consistent with roughly equal asteroidal and cometary contributions, while the latter would indicate mostly asteroidal contributions.
• The former enhancement is consistent with roughly equal asteroidal and cometary contributions, while the latter would indicate mostly asteroidal contributions.
• They are also the most common class of carbon molecule in meteorites and in cometary and asteroidal dust ( cosmic dust ).
• Spectroscopical measurements in infrared indicate that Pasiphae is a spectrally featureless object, consistent with the suspected asteroidal origin of the object.
• Some scientists claim that the ultimate goal of the mission was to link Eros, an asteroidal body, to meteorites recovered on Earth.
• In the near term, relatively straightforward methods can be used to extract aluminum, iron, oxygen, and silicon from lunar and asteroidal sources.
• Sources of Solar System dust include comet dust, asteroidal dust, dust from the Kuiper belt, and interstellar dust passing through the Solar System.
• The group reported their discovery to the Central Bureau for Astronomical Telegrams as an asteroidal object, which was subsequently forwarded to the Minor Planet Center.
• The orbits of the Earth and most asteroids are very distant from each other in terms of delta-v and the asteroidal bodies have enormous momentum.
• The cometary and asteroidal delivery of water to accreting Earth and Mars has significant caveats, even though it is favored by D / H isotopic ratios.
• It was formally announced on October 14 in IAUC 3878 along with optical confirmation by Charles T . Kowal, who reported it to be asteroidal in appearance.
• He has been an amateur astronomer since 1977, a member of the Moscow Astronomy Club since 2002 and the head of a working group on asteroidal occultations.
• Later, he, along with scientists elsewhere, proposed that a certain unusual class of meteorites was not asteroidal in origin but instead came from the planet Mars.
