The planets, in order of their distance outward from the Sun, are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
Where is Voyager 1 now?
Voyager 1 is now billions of miles outside the heliopause, as far from that boundary as Neptune is from Earth, and speeding onward at about a million miles a day. And it’s still making remarkable discoveries, said Rankin. “Even at that distance, it still sees effects from the sun.

What’s the Closest Planet to Earth? Venus, Mars, Mercury Distance.
Which planet is the hottest?
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 its dense atmosphere make it our solar system’s hottest planet.
Is there a 10th planet?
Because Eris was initially thought to be larger than Pluto, it was described as the “tenth planet” by NASA and in media reports of its discovery.
Does a planet 9 exist?
Planet Nine is a hypothetical planet in the outer region of the Solar System. Its gravitational effects could explain the peculiar clustering of orbits for a group of extreme trans-Neptunian objects (ETNOs), bodies beyond Neptune that orbit the Sun at distances averaging more than 250 times that of the Earth.

Will Voyager 1 leave the Milky Way?
In August 2012, Voyager 1 became the first spacecraft to cross into interstellar space. However, if we define our solar system as the Sun and everything that primarily orbits the Sun, Voyager 1 will remain within the confines of the solar system until it emerges from the Oort cloud in another 14,000 to 28,000 years.
Will Voyager 1 ever stop?
How long can Voyager 1 and 2 continue to function? Voyager 1 is expected to keep its current suite of science instruments on through 2021. Voyager 2 is expected to keep its current suite of science instruments on through 2020. The radioisotope thermoelectric generator on each spacecraft puts out 4 watts less each year.
Is Voyager 1 broken?
In May 2022, Voyager 1 began transmitting incorrect telemetry to Earth. At the same time, despite the incorrect data, the AACS system continued to keep the device’s antenna pointed at Earth, which meant that it was still performing its main task.

Is Smiley a planet?
Measuring about 108–167 kilometres in diameter, it was discovered in 1992 by David C. Jewitt and Jane X. Luu at the Mauna Kea Observatory, Hawaii. After the discovery, they dubbed the object “Smiley” and it was shortly hailed as the tenth planet by the press.
Is there a 100th planet?
Astronomers have announced the discovery of the 100th planet known to inhabit another solar system. The star is 100 light years from Earth in the southern constellation Grus, or The Crane. The planet, one and a half times the mass of Jupiter, has a roughly circular orbit, like those of the sun’s family of planets.
