Comet Shoemaker–Levy 9 (formally designated D/1993 F2) was a comet that broke apart in July 1992 and collided with Jupiter in July 1994, providing the first direct observation of an extraterrestrial collision of Solar System objects. [5]
1.1 Falling into Jupiter. 4 comments. 1.2 Since neutrinos (and dark matter) don't interact with light, so what should happen when light comes across them? 19 comments.
At one point, the two may fall into sync, at which time Jupiter's constant gravitational tugs could accumulate and pull Mercury off course, with 1–2% probability, 3–4 billion years into the future. This could eject it from the Solar System altogether [1] or send it on a collision course with Venus, the Sun, or Earth. [10]
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). Instruments on Galileo detected a fireball that reached a peak temperature of about 24,000 K (23,700 °C; 42,700 °F), compared to the typical Jovian cloud-top temperature of ...
A SpaceX Falcon Heavy rocket carrying NASA's Europa Clipper space probe launches from Kennedy Space Center on Oct. 14, 2024, on a mission to orbit Jupiter and study its icy moon, Europa, for signs ...
DE440 and DE441 were published in 2021, with improvements in the orbits of Jupiter, Saturn and Pluto from more recent spacecraft observations. [7] JPL ephemerides have been the basis of the ephemerides of sun, moon and planets in the Astronomical Almanac since the volumes for 1984 through 2002, which used JPL's ephemeris DE200.
[needs update] After entry into the Jupiter system, Europa Clipper will perform a flyby of Ganymede at an altitude of 500 km (310 mi), which will reduce the spacecraft velocity by ~400 m/s (890 mph). This will be followed by firing the main engine at a distance of 11 Rj (Jovian radii), to provide a further ~840 m/s (1,900 mph) of delta-V ...
Bitcoin could soar to $500,000 if Trump creates a national reserve, Bitwise CIO Matt Hougan said.. The US creating a national stockpile will influence other countries to follow suit, he predicted ...
