Are you still feeling the effects of a new year? What would it be like to do it all again in a week? If you lived on a planet three times the size of Jupiter, you'd have to live there every five days for the rest of your life.
An example of a so-called "hot Jupiter," a world similar to our solar system's largest planet, the gas giant Jupiter, is located in extreme proximity to its star. The proximity gives rise to extreme conditions, such as surface temperatures hot enough to cause iron to evaporate in under ten days.
The star TOI-778 is around 6 million miles away from this hot Jupiter. The closest planet in the solar system is Mercury, which is approximately 29 million miles away from our star.
Mysterious hot Jupiter planets can be formed quickly or slowly.
The planet TOI-778 b is almost three times larger than Jupiter. The TOI-778 b is estimated to have a surface temperature of around 2200 degrees F.
Our star is 40% more mass than the parent star of the planet. The TOI-778 is a rapid rotator and spins at around 100,000 miles per hour. The star is less than half the age of the sun and has a surface temperature of over 11,000 degrees.
The TOI-778 b was spotted by the astronomer led by Jake T. Clark. Over 6,000 candidate exoplanets have been identified by TESS as TESS objects of interest.
There are over 5,000 known planets outside the solar system.
Clark and his team spotted a dip in the light output of TOI-778 caused as the planet crosses the face of its parent star from our perspective here on Earth. Ground-based telescopes were used to confirm the planetary nature of TOI-778 b.
Clark and his team found that the TOI-778 b is very close to the stellar equator. They think that the planet came to this position by moving through the disk of its host star rather than going through a chaotic process.
Clark and his co-authors suggest that disk migration is the likely cause of Jupiter's evolution.
