NASA scientists just announced the discovery of the youngest planet every found in the universe. The planet is named
K2-33b
, and closely orbits a new star — which makes the planet very hot.
Is Mercury the youngest planet?
Is it the oldest planet, or the youngest? Actually, you might be surprised to know that
there is no oldest or youngest planet
. Mercury is exactly the same age as all the rest of the planets in the Solar System: approximately 4.6 billion years old.
What is the youngest planet ever?
The
hot Jupiter exoplanet V830 Tau b
, published in the same issue of the journal Nature as the discovery of K2-33b, is the youngest known exoplanet with an age of around 2 million years (around the time that humans evolved on Earth).
What is the youngest thing in our solar system?
The protostar
and its protoplanetary disk are still in the process of being born. In a stellar nursery far away, a solar system with enough heft to make seven Jupiters is in the process of being born, the youngest planetary system ever observed. The system is just 300,000 years old, astronomers say.
Which planet is very old?
Jupiter
is oldest planet in solar system, ancient meteorites show. Jupiter 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.
What is the hottest planet in the universe?
Planetary surface temperatures tend to get colder the farther a planet is from the Sun.
Venus
is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet.
What was the first planet discovered?
In fact, because these planets had been known to people for millennia,
Uranus
was arguably the first planet in recorded history to have been ‘discovered’ at all.
How old is our sun?
The sun was born
about 4.6 billion years ago
. Many scientists think the sun and the rest of the solar system formed from a giant, rotating cloud of gas and dust known as the solar nebula.
Which planet has the largest number of satellites?
| Planet / Dwarf Planet Confirmed Moons Provisional Moons | Jupiter 53 26 | Saturn 53 29 | Uranus 27 0 | Neptune 14 0 |
|---|
What is the biggest star?
Although it’s difficult to pin down the exact traits of any given star, based on what we know, the largest star is
UY Scuti
, which is some 1,700 times as wide as the Sun.
How old is Jupiter?
Jupiter 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 Jupiter is about 4.6 billion years old.
Which planet has the coldest atmosphere?
The seventh planet from the sun,
Uranus
has the coldest atmosphere of any of the planets in the solar system, even though it is not the most distant.
Is Venus hot or cold?
Although Venus is not the planet closest to the sun, its dense atmosphere traps
heat
in a runaway version of the greenhouse effect that warms Earth. As a result, temperatures on Venus reach 880 degrees Fahrenheit (471 degrees Celsius), which is more than hot enough to melt lead.
Which is the only planet that can sustain life?
Understanding planetary habitability is partly an extrapolation of the conditions on
Earth
, as this is the only planet known to support life.
