what are the oldest known objects in the solar system?


In Sivershchina, close to the village of Mizyn in Ukraine is one of the oldest and most unique settlements of humans – and it was discovered in a parking lot. Stars like the Sun hold 14 Jupiters worth.

FILE - Staff members of Juno Mission watch on before the solar-powered Juno spacecraft went into orbit around Jupiter, at NASA's Jet Propulsion Laboratory in Pasadena, Calif., on July 4, 2016. Therefore the upper bound on the uncertainty of the age of ALH84001 is unrealistic.

The following sentences in the lead are repeated word-for-word in the "Oldest terrestrial material" section: I've removed the following as it contains innaccuracies and over generalizations from the referenced article. Best I can tell looking at the initial paper the measurements for the oldest part of this rock were 4.40±0.11 billion years with the 4.46 figure being their estimated age of the crust: Astronomers around the world are monitoring an interstellar comet hurtling through the solar system, known for the moment as C/2019 Q4. They are 4.28 billion years old, making them 250 million years more ancient than any previously discovered rocks.Can any body find the correct wiki article that describes the method for dating the crystals?

C- Shouldn't the rocks on earth section (or some other part of the article) make mention of the Apollo moon rocks? It is possible that SiC interplanetary dust particles are older (as they may not have an origin in our solar system) but they have not yet been reliably dated.Rickert 23:30, 27 September 2007 (UTC)

I have a source that says the Australian Zircon fragments have radiometric ages of around 4150Zircon from the Jack Hills (western Australia) have a wide range in ages, including 4.15 Ga, although the oldest is 4.404 Ga. They are expected to be among the oldest, if not THE oldest solar objects. Hananoshi 13:14, 24 August 2008 (UTC) It is widely known that ancient space rocks floating through the solar system are amongst the oldest bodies in the solar system. "How the asteroid came to move in this way, while sharing Jupiter's orbit, has until now been a mystery," Namouni explained. They are expected to be among the oldest, if not THE oldest solar objects. Has it to do with the decay of uranium? Until last month, Eris was, with the exception of some long-period comets, the most distant object known in the Solar System. Mercury Meteorite NWA 7325 is estimated to be 4.56 billion years old and was likely ejected from Mercury on an Earth-intersecting trajectory by an impact They're much older than the oldest terrestrial rocks, and they're on earth now. Scientists say they are unsure about the materials it is made of.BZ travels in the opposite direction of all the planets and nearly everything else in our solar system.

Now researchers believe they have discovered the oldest alien object. ‘Alien Asteroid’ Could Be Oldest Object in Our Solar System
Start studying joey chapter 27 planets and solar system. They said that evidence suggests the asteroid formed elsewhere and was captured by gravitational forces when our solar system was formed.The researchers believe the sun, planets and other objects in our solar system formed from a Fathi Namouni is an astronomer with the Observatoire de la Côte d’Azur in France.

Keen insight, but ridiculous. She said the movement of BZ is similar to that of the planet Jupiter.“They complete an orbit around the sun in the same amount of time while moving in opposite directions,” she said.BZ may be important in discussions about the development of life on Earth.“This discovery tells us that the solar system is likely to be home to more extra-solar asteroids and The researchers said a number of other solar system objects with retrograde orbits are being investigated as possible “alien asteroids.”___________________________________________________________________________________________________________________________
