Sentences with phrase «sun orbital distance»

Giant stars Aa and Ab are separated by less than the Earth - Sun orbital distance (around 0.73 AU).

Not exact matches

Their search was sensitive up to distances corresponding to about twice the orbital periods of these so - called hot Jupiters, or about one - tenth of the distance between Mercury and the sun.

The group defined a plutoid as an object orbiting the sun at an average distance greater than Neptune's, massive enough to assume a nearly spherical shape (as planets do) but not massive enough to clear its orbital path of other bodies (as planets also do).

Astronomers have understood the relative spacing of the planets since 1619, when German mathematician Johannes Kepler published his third law of motion, which relates each body's orbital speed to its distance from the sun.

Still, its sun is smaller and cooler than ours, and Gliese 667Cc's orbital distance means it probably receives around 90 percent of the energy we get from the sun.

Based on photographs taken between 1937 and 1970, Sarah Lee Lippincott reported in 1971 that star A and B are separated by an «average» distance of 147 times the Earth - Sun distance (AU)(of a semi-major axis) in a circular orbit (e = 0.00) of about 2,600 years, in contrast to Josef Hopmann's (1890 - 1975) earlier report in 1958 of an elliptical orbit (e = 0.25) with an orbital period of 3,000 years and an «average» distance of 157 AU (of a semi-major axis) that varies between 118 and 196 AU.

At their closest approach, Stars A and B are about two AUs farther apart than the average orbital distance of Saturn around the Sun, while their widest separation is still about six AUs farther the average orbital distance of Neptune.

As an example, Mars orbits the Sun at a mean orbital distance of 1.52 AU and thus can be observed as close as ~ 0.5 AU from the Earth.

The two stars are separated «on average» by only 3.1 times the Earth - Sun distance — 3.1 astronomical units (AUs) of an orbital semi-major axis (a = 0.715 + / -0.04»).

For perspective, Pluto orbits the sun at an average distance of 40 AU, with a maximum orbital distance of 49 AU.

Sirius A and B form a close binary separated «on average» by only about 19.8 AUs of an orbital semi-major axis — which is about the same as the distance between Uranus and our Sun («Sol»).

Since a 2005 visit by NASA's Deep Impact spacecraft, the short - period comet has completed more than one complete orbit around the Sun and approached the inner Solar System as close as the orbital distance of Mars.

Habitable zone planets around Sun - like stars, plotted with their orbital distance versus either planetary mass or radius.

Early in 2002, S2 came very close to the black hole, coming within 17 light - hours or around three times the orbital distance of Pluto from the sun (or 39 AUs).

In the early 1990s, one study found that coplanarity between the orbital and equatorial planes of nearby binaries (within 100 parsecs or 326 ly) that are composed of Sol - type stars (F5 - K5 V) «exists» for binaries with orbital separations up to the average orbital distance of Pluto in the Solar System — roughly 40 times the Earth - Sun distance or «astronomical unit» (AU).

We love the beautifully engraved details, which include planet names and distances from the sun as well as orbital periods and asteroids.
