Astronomers have discovered that a distant, scorching hot planet twice the size of Jupiter is on a death-spiral trajectory that will send it careening into its parent star. A crash is expected to happen relatively soon, cosmically speaking., will eventually take a dive into its star that's located around 1,400 light years from Earth. However, these new findings have shortened the time WASP-12b has left.
In other words, this may seem like an incredibly long time, but the fact that stars like the sun live for around 10 billion years means it is a very short period on cosmic scales.so closely that it almost fits an entire year into a single Earth day. This proximity classifies WASP-12b as an"" planet, a name that is fitting considering radiation from this star ceaselessly belts the planet, giving it a surface temperature of around 4,000 degrees Fahrenheit .
Leonardi and colleagues investigated the timing variation of WASP-12b by looking at 28 observations of the planet taken as it crossed, or"transited," the face of its parent star. This was done in collaboration with the Asiago Search for Transit Timing Variations of Exoplanets project. These observations were collected over a period of 12 years between 2010 and 2022 by the Asiago Observatory in Italy.
"However, according to our results, the star is still in the main sequence and has not yet entered its sub-giant stage." "When the planet inevitably crashes into the star, the first indication will be an outburst of luminosity, which will see the star become hundreds of times brighter than it is today," Leonardi said."This increase will not last long and will quickly fade away. But maybe the humans of the future could be there to see it and study it.
