The whopper sun emits light in similar wavelengths as our sun but its diameter is over 1300 times larger. That means it would engulf all the planets between Mercury and Jupiter if placed at the centre of our solar system.

What planet is 10 times the size of Earth?
The mysterious world, nicknamed Planet Nine, is about 10 times more massive than the Earth, thought to be gaseous, and similar to Uranus or Neptune. Scientists believe it traces a highly elongated orbit and takes between 10,000 and 20,000 years to make just one journey around the sun.
What are the 9 planets?
Here’s the order of the planets, starting nearest the sun and working outward through the solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune — and Planet Nine.

Is Pluto a planet in 2018?
In 2006, Pluto was reclassified as a “dwarf planet.” This had two yet know about? In December 2018, astronomers announced they’d found the
Are there 13 planets in our solar system?
There are eight planets in the solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Our solar system is an orderly arrangement of planets orbiting the Sun. NASA. Pluto, a dwarf planet, was classified as one of the solar system planets when it was first discovered by Clyde Tombaugh.
What planets are larger than Earth?
The largest planet in our solar system by far is Jupiter, which beats out all the other planets in both mass and volume. Jupiter’s mass is more than 300 times that of Earth, and its diameter, at 140,000 km, is about 11 times Earth’s diameter.
Is the sun bigger than the Jupiter?
Jupiter is much larger than Earth and considerably less dense: its volume is that of about 1,321 Earths, but it is only 318 times as massive. Jupiter’s radius is about 1/10 the radius of the Sun, and its mass is 0.001 times the mass of the Sun, so the densities of the two bodies are similar.
What is the biggest planet known to man?
What’s The Largest Planet In The Universe?
- The exoplanet Kepler-39b is one of the most massive ones known, at 18 times the mass of Jupiter, placing it right on the border between planet and brown dwarf.
- A cutaway of Jupiter’s interior.
- WASP-17b is one of the largest planets confirmed not to be a brown dwarf.
What is the oldest planet?
It is also the first planet found in a globular cluster. The planet is one of the oldest known extrasolar planets, believed to be about 12.7 billion years old.
What year is it on Mars?
How did planets form?
The various planets are thought to have formed from the solar nebula, the disc-shaped cloud of gas and dust left over from the Sun’s formation. The currently accepted method by which the planets formed is accretion, in which the planets began as dust grains in orbit around the central protostar.
Where is Planet 9 located?
Planet Nine is a hypothetical planet in the outer region of the Solar System.
What is the closest Earth like planet?
The nearest such planet may be as close as 12 light-years away. On August 24, 2016, astronomers announced the discovery of a rocky planet in the habitable zone of Proxima Centauri, the closest star to Earth (not counting the Sun).
Which planet is Planet A?
 The eight planets are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Under this definition, the Solar System is considered to have eight planets.
How many known planets exist in the universe?
On November 4, 2013, astronomers reported, based on Kepler space mission data, that there could be as many as 40 billion Earth-sized planets orbiting in the habitable zones of Sun-like stars and red dwarf stars within the Milky Way galaxy. 11 billion of these estimated planets may be orbiting Sun-like stars.
Why is Pluto no longer a planet?
In 2005, Eris, a dwarf planet in the scattered disc which is 27% more massive than Pluto, was discovered. This led the International Astronomical Union (IAU) to define the term “planet” formally in 2006, during their 26th General Assembly. That definition excluded Pluto and reclassified it as a dwarf planet.
How many galaxies are in the universe?
Several thousand galaxies, each consisting of billions of stars, are in this small view. XDF (2012) view: Each light speck is a galaxy, some of which are as old as 13.2 billion years – the observable universe is estimated to contain 200 billion to 2 trillion galaxies.
Will the sun die?
By that point, all life on the Earth will be extinct. The most probable fate of the planet is absorption by the Sun in about 7.5 billion years, after the star has entered the red giant phase and expanded beyond the planet’s current orbit.
What is the oldest living thing on earth?
Methuselah, a Great Basin bristlecone pine (Pinus longaeva) is measured by ring count to be 4,850 years old. This is the oldest known tree in North America, and the oldest known living individual nonclonal tree in the world. The Cypress of Abarkuh is estimated to be between 4,000 and 5,000 years old.
What is the oldest thing in the universe?
With a redshift of z = 8.2, at the time of observation, the burst was the most distant known object of any kind with a spectroscopic redshift. GRB 090423 was also the oldest known object in the Universe, as the light from the burst took approximately 13 billion years to reach Earth.
Can we live on Mars?
Human survival on Mars would require living in artificial Mars habitats with complex life-support systems. One key aspect of this would be water processing systems. Being made mainly of water, a human being would die in a matter of days without it.
What color is the sky on Mars?
The normal hue of the sky during the daytime is a pinkish-red; however, in the vicinity of the setting or rising sun it is blue. This is the exact opposite of the situation on Earth. However, during the day the sky is a yellow-brown “butterscotch” color. On Mars, Rayleigh scattering is usually a very small effect.
How long does a day last on Mars?
1d 0h 37m
How was Earth created?
Earth formed around 4.54 billion years ago, approximately one-third the age of the universe, by accretion from the solar nebula. Volcanic outgassing probably created the primordial atmosphere and then the ocean, but the early atmosphere contained almost no oxygen.
What type of planet is Earth?
A terrestrial planet, telluric planet, or rocky planet is a planet that is composed primarily of silicate rocks or metals. Within the Solar System, the terrestrial planets are the inner planets closest to the Sun, i.e. Mercury, Venus, Earth, and Mars.
How was universe created?
Soon after the Big Bang, primordial protons and neutrons formed from the quark–gluon plasma of the early Universe as it cooled below two trillion degrees. A few minutes later, in a process known as Big Bang nucleosynthesis, nuclei formed from the primordial protons and neutrons.
What planets can support life?
On 4 November 2013, astronomers reported, based on Kepler space mission data, that there could be as many as 40 billion Earth-sized planets orbiting in the habitable zones of Sun-like stars and red dwarfs within the Milky Way.
What is the most habitable planet besides Earth in our solar system?
Despite this, some scientists estimate that there are as many habitable exomoons as habitable exoplanets. Given the general planet-to-satellite(s) mass ratio of 10,000, large Saturn or Jupiter sized gas planets in the habitable zone are thought to be the best candidates to harbour Earth-like moons.
Are there planets in other galaxies?
An extragalactic planet, also known as an extragalactic exoplanet, is a star-bound planet, or rogue planet, located outside of the Milky Way Galaxy. Due to the huge distances to such worlds, they would be very hard to detect directly. However, indirect evidence suggests that such planets may exist.
