WASP-17 b (auch „WASP-17b“ geschrieben) ist ein Exoplanet, der den Stern WASP-17 im Sternbild Skorpion umkreist.Er hat die bisher geringste bekannte Dichte eines Planeten und zudem eine rückläufige Umlaufbahn.In seiner Atmosphäre wurde Wasserdampf nachgewiesen.. Eigenschaften. It is the first planet discovered to have a retrograde orbit, meaning it orbits in a direction counter to the rotation of its host star.This discovery challenged traditional planetary formation theory. Music: Oliver Lieb-WASP-17b (Cid Inc. Remix) Video: Azarkant ( Short Film) Although jupiter is like an ant in comparison to Jupiter, this planet is only half the mass of Jupiter. It is the first planet to have a retrograde orbit, meaning, it rotates in the direction opposite of … Global topics []. Discovered in 2009, it is twice the radius of Jupiter, but only 48.6% of the mass. [1] WASP-17b is in a 3.7-day orbit around a sub-solar metallicity, V = 11.6, F6 star. Preliminary detection of the Rossiter-McLaughlin effect suggests that WASP-17b is in a retrograde orbit (lambda ~ -150 deg), indicative of a violent history involving planet-planet or star-planet scattering. That means the planet is spinning in the opposite direction of its star. The unusually low density is thought to be a consequence of a combination of the planet's orbital eccentricity and its proximity to its parent star (less than one seventh of the distance between Mercury and the Sun), leading to tidal flexing and heating of its interior. WASP-17b on eksoplaneetta, joka löydettiin 11. elokuuta 2009. Such photometric observations also reveal the planet's size. List of 10,000 articles every Wikipedia should have; Indian topics []. Se kiertää keltavalkoista F-tyypin pääsarjan tähteä WASP-17 Skorpionin tähdistön suunnalla. The Delaware State Lady Hornets (2-5, 0-0 MEAC) host the Morgan State Lady Bears (5-2, 0-0 MEAC) in MEAC action at Memorial Hall (Dover, DE) on Sunday, January 17, 2021. Se oli ensimmäinen eksoplaneetta, jonka havaittiin kiertävän tähteään retrogradisella radalla (tähden pyörimissuuntaa vastaan). Exoplanetary sodium in the atmosphere of the WASP-17 has been detected. Other recent examples are the detection of sodium in WASP-17b (Zhou & Bayliss 2012) and sodium and potassium in XO-2b (Sing et al. From top left to lower left, these planets are WASP-12b, WASP-6b, WASP-31b, WASP-39b, HD 189733b, HAT-P-12b, WASP-17b, WASP-19b, HAT-P-1b and HD 209458b. The name was selected in the NameExoWorlds campaign by Costa Rica, during the 100th anniversary of the IAU. Die Masse des Planeten beträgt etwa 0,5 Jupitermassen, sein Radius 1,5 bis 2 Jupiterradien. WASP-17B is made of a several material we don’t have on earth, but after a lot of research, this material seems reactive to certain gasses exposing the actual volume of this planet. Föhring D, Dhillon VS, Madhusudhan N et al (2013) ULTRACAM z ′-band detection of the secondary eclipse of WASP-12b. 4. This exoplanet could therefore be a hybrid world of rock and atmosphere, a carbon-rich world with a diamond mantle, a silicon-rich world covered in seas of supercritical fluids or even a world swimming in magma. For example, the radii vs mass observations of exoplanets such as 55 Cancri e implied it was too small to be a purely gas world but too large to be a rocky one. WASP-17b (Anderson et al. Read more at JPL-NASA. Its discovery was announced on 11 August 2009. WASP-17b umrundet seinen Hauptstern etwa alle 3,7 Tage einmal. WASP-17b, HD209458b, WASP-12b, WASP-19b and XO-1b (December 4, 2013) While not new entries, these were added as systems of interest due to the fact that these are believed to … WASP-17b is an exoplanet in the constellation Scorpius that is orbiting the star WASP-17. Credit NASA. The two research teams used Hubble's Wide Field Camera 3 to analyze starlight passing through the atmospheres of the five "hot Jupiter" planets, which are known as WASP-17b, HD209458b, WASP-12b, WASP-19b and XO-1b. MNRAS 435:2268–2273 Google Scholar Fortney JJ, Demory BO, Désert JM et al (2011) Discovery and atmospheric characterization of giant planet Kepler-12b: an inflated radius outlier. The planet has mass half that of Jupiter, but its insolation has forced a thermal expansion of its radius over that of Jupiter. [11] Kepler-7b orbits its host star every 4.8855 days at a distance of 0.062 24 AU , making it the furthest-orbiting planet of the first five discovered by Kepler. HAT-P-32, or GSC 3281-00800, is a G-type or F-type dwarf star located some 320 parsecs (1,044 light years) away from Earth.With 1.176 solar masses and 1.387 solar radii, HAT-P-32 is both larger and more massive than the Sun.

It has a mass close to that of Jupiter (1.15 Jupiter masses ), but by comparison has a much larger radius (1.31 times that of Jupiter, or 0.13 Solar radii ); making it nearly the size of a low-mass star. Such low densities are not predicted by current standard theories of planet formation. List of articles each Indian language Wikipedia should have; Local topics []. Welcome to Beatport. Spin-orbit angle measurement was updated in 2012 to -148.7+7.7−6.7°.[13]. In 2009, scientists discovered WASP-17b, a huge planet that might be almost twice as big as Jupiter. The matchup tips at 1:00 PM ET. This is also one of the largest planet in the solar system.

Thus its mean density is between 0.08 and 0.19 g/cm 3, compared with Jupiter's 1.326 g/cm 3 and Earth's 5.515 g/cm 3 (the density of water is 1 g/cm 3). <
