Sentences with phrase «longer orbital periods»

Thus far, Kepler has found 48 planetary candidates in their host star's habitable zone (of which 10 are near Earth - size), but this number is a decrease from the 54 reported in February 2011 only because the Kepler team is now applying a stricter definition of what constitutes a habitable zone around stars to account for the warming effect of planetary atmospheres, which would move such a zone away from the star, outwards in orbital distance resulting in longer orbital periods (NASA news release; and Kepler Press Conference slides — in pdf).

The progression toward smaller planets at longer orbital periods with each new catalog release suggests that Earth - size planets in the Habitable Zone are forthcoming if, indeed, such planets are abundant.

Observing multiple orbits of cooler planets with longer orbital periods will take much more time.

The co-authors suggest that future studies looking to find and study possibly habitable planets around short - term binary stars should focus on those with longer orbital periods than about 7.5 days.

Due to its long orbital period, Kepler 452 b barely met that minimal criterion before the telescope's primary mission ended — but a host of other, more technical tests convinced the Kepler team the planet had a 99 percent chance of being real.

(Hint — it relates to the longest orbital period... for example, Saturn takes 29.4 years to circle the sun...)

Led by Renu Malhotra, a Regents» Professor of Planetary Sciences in the UA's Lunar and Planetary Lab, the team found that the four Kuiper Belt Objects with the longest known orbital periods revolve around the Sun in patterns most readily explained by the presence of a hypothetical «Planet Nine» approximately ten times the mass of Earth.

Some years ago, when AAAS launched an effort to reform science education, it said that true reform will take about as long as Halley's Comet's orbital period [of about 76 years]-- that's why they labeled their initiative Project 2061.

These moons have orbital periods exactly 2 and 4 times as long as Io's, which results in the three moons lining up every so often.

By tracking the frequency at which certain starspots reappeared, Sanchis - Ojeda determined that the star completes a full rotation every 12.5 days — considerably longer than the planet's orbital period of 8.5 hours.

The more common exoplanet search technique, measuring stellar gravitational wobbles, would require one to two decades and longer to identify the orbital periods of planets at the distances of Jupiter and Saturn.

«Simply put, if the black hole is small, the orbital periods at the innermost circular orbit are shorter, but if the black hole is big, the orbital periods are longer (smaller frequencies).»

This planet would most likely orbit Alpha Centauri B with an orbital period of 20.4 days or less, with only a 5 percent chance of it having a longer orbit.

And moving away its orbital period will get slightly longer so the tides will get slightly more spread out.

This planet has an orbital period similar to that of HD 209458b, but about twice as long as those of the OGLE transiting planets.

However, if the existence of a relatively close, second companion (see Star Bc below) around Bab — with an orbital period of 2.2 to 2.9 years or less — is confirmed, then a planetary orbit in Star Ba's water zone may not be stable over the long run.

Astronomers who attempted to map Mercury thus agreed that the planet probably had a rotation period as long as its orbital period.

Long Period Comets (Non-periodic comets) are comets that do not have confirmed observations at more than one perihelion passage and generally have orbital periods of 200 years or more.

Short orbital - period comets are thought to originate from the Kuiper Belt, while long orbital - period comets are believed to be from the Oort Cloud.

Comet Hale - Bopp, which was visible to the naked eye for 18 months spanning 1996 and 1997, is a long orbital - period comet that won't be visible from Earth again for several thousand years.

Most extrasolar giant planets with orbital periods longer than two weeks have elongated orbits.

Comets travel in an orbit; a short orbital - period comet is one that takes 200 years or less to go around the Sun, and a long orbital - period comet takes more than 200 years — often thousands or even millions of years.

Star A, however, is no longer thought to have a spectroscopic binary companion with a nine - day orbital period (Morbey and Griffin, 1987; and Helmut Abt, 1987).

The orbital period of Pluto is 248 years, and so it spends long times near these points — long enough to come to some sort of quasi-equilibrated average temperature.

It has been suggested that Stage 11 was an extraordinarily long interglacial period because of its low orbital eccentricity, which reduces the effect of climatic precession on insolation (Box 6.1)(Berger and Loutre, 2003).

Based just on orbital forcing, and following previous ice age cycles, we are due for a long period of gradual cooling to the next ice age.
