“#Venus answers how long is the solar system’s longest day<\/strong>”<\/p>\n

Data obtained by bouncing radio waves off Venus \u2013 treating it, as one scientist said, like a giant disco ball \u2013 is providing new insight into Earth\u2019s closest planetary neighbor, including a precise calculation of the duration of a Venusian day.<\/p>\n

The study also measured the tilt of the Venusian axis and size of the planet\u2019s core, allowing for a deeper understanding of an enigmatic world sometimes called Earth\u2019s \u2018evil twin.\u2019<\/p>\n

It was already known that Venus has the longest day \u2013 the time the planet takes for a single rotation on its axis \u2013 of any planet in our solar system, though there were discrepancies among previous estimates.<\/p>\n

The study found that a single Venusian rotation takes 243.0226 Earth days. That means a day lasts longer than a year on Venus, which makes a complete orbit around the sun in 225 Earth days.<\/p>\n

The researchers transmitted radio waves toward Venus 21 times from 2006 to 2020 from NASA\u2019s Goldstone Antenna in the Mojave Desert of California and studied the radio echo, which provided information on certain planetary traits, at Goldstone and at the Green Bank Observatory in West Virginia.<\/p>\n

\u201cEach individual measurement was obtained by treating Venus as a giant disco ball. We illuminated Venus with a giant flashlight, the radar at Goldstone and observed the reflections as they swept over the surface of the Earth,\u201d said UCLA planetary astronomy professor Jean-Luc Margot, who led the study published in the journal Nature Astronomy.<\/p>\n

\u201cVenus is an amazing laboratory for understanding planet formation and evolution and it\u2019s a stone\u2019s throw away. There are likely billions of Venus-like planets in the galaxy,\u201d Margot added.<\/p>\n

The new data showed that the Venusian planetary core has a diameter of about 4,360 miles, comparable to Earth\u2019s core. Previous Venus core estimates had been based on computer modeling rather than observational data.<\/p>\n

Its core is almost certainly composed of iron and nickel, though it is unclear whether it is solid or molten, Margot said.<\/p>\n

Venus spins on its axis almost upright \u2013 meaning it lacks discernable seasons \u2013 while Earth has more of a tilt. The study calculated the Venusian tilt at about 2.64 degrees. Earth\u2019s is about 23.5 degrees.<\/p>\n

Venus, the second planet from the sun, is similar in structure but slightly smaller than Earth, with a diameter of about 7,500 miles. Above its foreboding landscape is a thick and toxic atmosphere that consists primarily of carbon dioxide, with clouds of sulfuric acid droplets. With a runaway greenhouse effect, its surface temperatures reach 880 degrees Fahrenheit, hot enough to melt lead.<\/p>\n

Venus spins from east to west, the opposite direction from all other planets in our solar system but Uranus. In another quirk, its day-night cycle \u2013 the time between sunrises as opposed to the length of a single axial spin \u2013 takes 117 Earth days because Venus rotates in the direction opposite of its orbital path around the sun.<\/p>\n

Venus has received less scientific attention than Mars, Earth\u2019s other planetary next-door neighbor and other solar system destinations.<\/p>\n

\u201cI don\u2019t think that Venus would be more difficult to understand than other planets if we had adequate data, but there is a deplorable scarcity of data about Venus,\u201d Margot said.<\/p>\n

\u201cThere have been no NASA missions to Venus in almost 30 years and about a dozen NASA missions to Mars in this time interval,\u201d Margot said, adding that the new findings on how Venus spins could help any future landing attempts.\n <\/p><\/div>\n
