The core of the Planet and the dead star give us a look at the future of the Earth



"We can say with certainty that it will not be the core of the gas giant, because they must have another composition," Manser says, "and the material that we see, who made a white dwarf,"

Instead , the planetzymal probably appeared deep inside a rocky planet that was torn when the star's host went from normal to bloated Red giant to white dwarf

"In our solar system, when the sun becomes a red giant, it will embrace Mercury , Venus and, of course, the Earth ", – says Manser. But in this experiment An enormous planetzymal probably is "distant in the system, as an analog of the asteroid belt, or a planet that is spinning further, and then scattered in a white dwarf." Menser claims that he was either pushing a white dwarf through interaction with giant planets or over ground and partially destroyed, or was torn as a result of a planet's collision with the planet, creating an asteroid similar to Psyche 1

6. Our own solar system, "before moving inward."

Planetesimal rotates about once every 40 minutes, and revolves around a white dwarf about once every two hours. In such a short orbital period, researchers expect the planetal to stay very close to its host star. In fact, according to the study, if instead of rotated around the Sun (which is approximately 100 times the diameter of a white dwarf), instead of literally sitting inside our star.

t be more elongated (or eccentric) than the almost circular orbit of your average planet, although Manser points to further details needed to confirm this eccentricity. Often, when an object has an extremely eccentric orbit, it indicates a powerful past interaction that drove it out of the circular orbit it received when it was originally formed in a circular protoplanetary disk. Thus, if the eccentric orbit is confirmed, it can serve as additional proof of the violent past of planetzizm. 70 percent of the mass of the Sun and located at a distance of 410 light years in the constellation Virgin. SDSS1228 is especially noticeable because it is a member of the ultra-rare white dwarf class that hosts planetary disks made of both dust and . Although Manser argues that there are 40 to 45 white dwarfs that are known to place discs exclusively from dust, only seven (or 0.07% of all white dwarfs) have discs that also contain gas.
