Duration of One Day Planet Neptune

Do you know the sky stretched above our heads that did not have the edge, by technological  progress people can easily see the state of the sky was very clear and the bias measure how the distance between them.  Tracking certain features in the atmosphere, the researchers managed to make the first accurate measurement of the rotation period of Neptune. 

 Apparently, one day on the planet that lasted just over 15 hours, 57 minutes and 59 second.The finding this enriches our knowledge about the fundamentals in Neptune and also provides a mechanism for understanding how the planet's mass is distributed. As is known, is a giant planet Neptune made of gas. Neptune has two features that allow it to be monitored by the Hubble Space Telescope, which seems to regulate the rotation of the planet's interior, "said Erich Karkoschka, scientists from the Lunar and Planetary Laboratory, University of Arizona, as quoted from Cosmos Magazine, July 4, 2011. Features like this, Karkoschka said, was never found in other giant
gas planets.

To find out how the duration of one day on the planet, Karkoschka putaranNeptunus measure by observing the two features that are invisible to the eye belongs to the planet's atmosphere. He then measured the longitude of each image is captured and then determine the time interval between observation and provide information rotated. Because period of Neptune has been rotated about 10 thousand times in the last 20 years, Karkoschka can know accurately the rotation period by tracking these features in period. The results of this study is a significant increase in knowledge of the rotational gas planets since the first successful Giovanni Cassini discovered the red spot of Jupiter, at 350 years ago. Currently among the scientists themselves seem to have emerged a consensus that the findings are accurate Karkoschka. According to Craig O'Neill, space scientists from Macquarie University, Australia, Markoschka findings about the period features of Neptune's atmosphere right. In addition, Karkoschka also showed that in the polar regions, wind speeds lower than in the past equator.What people only see the sky only, now people can measure and landed on the ground planet it.
