Putilin suggested that Phaeton was destroyed due to centrifugal forces, giving it a diameter of approximately 6,880 kilometers (slightly larger than Mars' diameter of 6,779 km) and a rotational speed of 2.6 hours.
Pluto never blew up. It was, however, disqualified as a planet and categorized as a dwarf planet. No. Pluto did not explode but, In August 2006 the International Astronomical Union (IAU) downgraded the status of Pluto to that of "dwarf planet."
The fall of an asteroid on Jupiter caused an explosion by the force of a nuclear bomb.
In 2022, Jupiter moved from Pisces to Aries and then back to Pisces (the sign it is currently residing in now) during the nearly four month retrograde cycle that began on July 28th.
Many lines of evidence suggest more than one planetary explosion in the Solar System's history. The discovery of one, and probably two, new asteroid belts orbiting the Sun beyond Neptune is especially suggestive, given that the main asteroid belt is apparently of exploded planet origin.
Strange, gigantic explosions fueled by solar energy detonate just above the surface of Venus, a new study finds. The huge eruptions, known as hot flow anomalies (HFAs), have been seen before near Earth, Saturn and possibly Mars.
In 2006 the International Astronomical Union (IAU) demoted the much-loved Pluto from its position as the ninth planet from the Sun to one of five “dwarf planets.” The IAU had likely not anticipated the widespread outrage that followed the change in the solar system's lineup.
This Planet Is Flinging Comets At Earth 'Like A Sniper'
Research suggests that Jupiter is flinging dangerous objects towards Earth. The Jupiter Shield theory proposes that the biggest planet in the solar system acts like a huge shield in space, deflecting dangerous debris away from Earth.
While Jupiter often protects Earth and the other inner planets by deflecting comets and asteroids, sometimes it sends objects on a collision course straight toward the inner planets.
2070s: crewed mission to Jupiter (likely the moon Callisto because it's sufficiently removed from the planet's intense radiation fields). 2080s: crewed mission to Saturn's moons (likely Titan and/or Enceladus). 2250: crewed mission to close exoplanets like Proxima Centauri (4.2 light-years away).
How many planet has been destroyed? Eventually, some worlds could be kicked out of orbit completely and become consigned to floating through space unattached to any stars. Raymond calculated that roughly 5 billion rocky worlds have been destroyed by gas giants.
Astronomers have spotted a bright flash from a huge space rock slamming into Jupiter. This impact flash, seen in October 2021, was the brightest one since comet Shoemaker-Levy 9 hit the planet in 1994. Impact flashes on other worlds are similar to meteorite strikes on Earth, but only the largest are visible from afar.
Essentially, Pluto had residual heat from when it was closer to the sun. However, the inertia starting to wear off and, as Pluto gets colder, more and more of its atmosphere will freeze back onto its surface and "disappear."
Venus' thick atmosphere traps heat creating a runaway greenhouse effect – making it the hottest planet in our solar system with surface temperatures hot enough to melt lead.
Pluto is a dwarf planet in the Kuiper Belt, a donut-shaped region of icy bodies beyond the orbit of Neptune. There may be millions of these icy objects, collectively referred to as Kuiper Belt objects (KBOs) or trans-Neptunian objects (TNOs), in this distant region of our solar system.
"Pluto's atmosphere has more gaseous methane at its warmer, higher altitudes, allowing for that gas to saturate and freeze directly on the mountain peaks tall enough to reach the enriched zone," he said. "At lower altitudes, the concentration of gaseous methane is lower, and it cannot condense."
Without Jupiter, the Earth would be pummeled by impacts from asteroids and comets, rendering our planet utterly uninhabitable.
Jupiter's environment is probably not conducive to life as we know it. The temperatures, pressures, and materials that characterize this planet are most likely too extreme and volatile for organisms to adapt to.
As the Sun shrinks, Jupiter will not be so gravitationally bound to it anymore, which will make it susceptible to encounters with passing stars every 20 million years or so. Either these bypassers will shove the unstable Jupiter from its orbit until it gets the hint — or one ginormous one kicks it out.
The first impact occurred at 20:13 UTC on July 16, 1994, when fragment A of the [comet's] nucleus slammed into Jupiter's southern hemisphere at about 60 km/s (35 mi/s).
Given that these comets only make up a small fraction of the total impact threat, our startling conclusion is that, overall, Jupiter is not friend but foe! Interestingly, when it comes to the asteroids and short-period comets, we found that the impact rate does not simply increase with Jupiter's mass.
It may be the biggest planet in our Solar System but it would still need more mass to turn into a second Sun. Jupiter is often called a 'failed star' because, although it is mostly hydrogen like most normal stars, it is not massive enough to commence thermonuclear reactions in its core and thus become a 'real star'.
A group of astronomers, including Avi Loeb at Harvard University, suggested Planet Nine may be a tiny black hole somewhere out in the Oort Cloud. If Planet Nine turns out to be Black Hole Nine instead, it's probably about the size of a grapefruit but about 5 to 10 times the mass of Earth.
The ability of these past sky surveys to detect Planet Nine was dependent on its location and characteristics. Further surveys of the remaining regions are ongoing using NEOWISE and the 8-meter Subaru Telescope. Unless Planet Nine is observed, its existence remains purely conjectural.
Astronomers searching for our solar system's elusive Planet Nine — a theoretical world that may lurk deep in a cloud of icy rocks far beyond the orbit of Neptune — have come up short once again.
