what's the oldest planet in our solar system？
JupiterJupiter formed in a geologic blink. Its rocky core coalesced less than a million years after the beginning of our solar system, scientists reported Monday in the Proceedings of the National Academy of Sciences.2017年6月12日
Thereof,What was the very first planet?
Jupiter was probably the first planet in the solar system to form, new research suggests. Its existence may have influenced how the planets evolved into the order we see today.
Correspondingly,Is Jupiter older than the sun?
Astronomers finally know how old Jupiter is. The gas giant's core had already grown to be 20 times more massive than Earth just 1 million years after the sun formed, a new study suggests.
Also asked,Is Venus older than Earth?
Whereas Earth's oceanic crust is continually recycled by subduction at the boundaries of tectonic plates, and has an average age of about 100 million years, Venus' surface is estimated to be 300–600 million years old.
Keeping this in consideration,What is the oldest planet and why is that the oldest?
Long before our Sun and Earth ever existed, a Jupiter-sized planet formed around a sun-like star. Now, 13 billion years later, NASA's Hubble Space Telescope has precisely measured the mass of this farthest and oldest known planet.
The sun, at 4.6 billion years old, predates all the other bodies in our solar system.
NASA's Hubble Space Telescope precisely measured the mass of the oldest known planet in our Milky Way galaxy. At an estimated age of 13 billion years, the planet is more than twice as old as Earth's 4.5 billion years. It's about as old as a planet can be.
4.503 billion years天王星 / AgeUranus was formed at the same time as the rest of the Solar System, from a large spinning disk of gas and dust. Astronomers think that all this happened about 4.6 billion years ago! So Uranus is about 4.6 billion years old.
4.53 billion years月球 / AgeThe moon is a very old soul, it turns out. A new analysis of lunar rocks brought to Earth by Apollo astronauts suggests that the moon formed 4.51 billion years ago — just 60 million years after the solar system itself took shape.
Last year, NASA announced it had located a planet and star closely resembling Earth and the sun. The newly discovered planet, which NASA has named Kepler-452b, is believed to be 6 billion years old -- making it about 1.5 billion years older than the Earth and our sun.
Some of the water molecules in your drinking glass were created more than 4.5 billion years ago, according to new research. That makes them older than the Earth, older than the solar system — even older than the sun itself.
Not all water in the Solar System today could have formed here, researchers say. As much as half of the water in Earth's oceans could be older than the Sun, a study has found.
Around 70 percent of the Earth's surface is comprised of water, and our big, blue, planet is filled with rivers, streams, and oceans that defy everything scientists have come to learn about the formation of Earth.
