Frequently Asked Questions

Voyager 1 is escaping the solar system at a speed of about 3.5 AU per year, 35 degrees out of the ecliptic plane to the north, in the general direction of the solar apex (the direction of the sun''s motion relative to nearby stars). Voyager 1 will leave the solar system aiming toward the constellation Ophiuchus.

Solar System Exploration

Our Sun: Facts

From our vantage point on Earth, the Sun may appear like an unchanging source of light and heat in the sky. But the Sun is a dynamic star, constantly changing and sending energy out into space. The science of studying the Sun and its influence throughout the solar system is called heliophysics. The Sun is []

Solar system | Definition, Planets, Diagram, Videos, & Facts

· The solar system''s several billion comets are found mainly in two distinct reservoirs. The more-distant one, called the Oort cloud, is a spherical shell surrounding the solar system at a distance of approximately 50,000 astronomical units (AU)—more than 1,000 times the distance of Pluto''s orbit. The other reservoir, the Kuiper belt, is a thick disk-shaped zone whose main

Solar System Facts

Our planetary system is called "the solar system" because we use the word "solar" to describe things related to our star, after the Latin word for Sun, "solis." 2. Our solar system orbits the center of the Milky Way galaxy at about 515,000 mph (829,000 kph).

What was the first man made object to leave our solar system?

The rather funny thing about it is, that we don''t actually know for sure that any man-made objects have already left the Solar system. There were many speculations on where our Solar system actually ends and the interstellar space begins, free of

5 NASA spacecraft that are leaving our solar system for good

Voyager 1 and Voyager 2. Half a century ago, NASA built its two identical Voyager spacecraft to capitalize on a rare alignment of the outermost planets that only happens once every 175 years.

NASA''s Voyager 2 Probe Enters Interstellar Space

While the probes have left the heliosphere, Voyager 1 and Voyager 2 have not yet left the solar system, and won''t be leaving anytime soon. The boundary of the solar system is considered to be beyond the outer edge of the Oort Cloud, a collection of small objects that are still under the influence of the Sun''s gravity. The width of the Oort

It''s Official: Voyager 2 Has Left Our Solar System And Is Sailing in

Voyager 2 has left the Solar System. After making a careful analysis of the data, scientists have confirmed it: like Voyager 1 before it, the little space probe is now out beyond the heliopause, and heading deeper into the vast unknown of interstellar space. And understanding our Solar System''s bubble could help us to understand the

5 space probes leaving the solar system (for now)

As of 2019, only five space probes are leaving the solar system: Pioneer 10, Pioneer 11, Voyager 1, Voyager 2, and New Horizons.The Voyagers already left the solar system and entered interstellar space (Voyager 1 on August 25, 2012, and Voyager 2 on November 5, 2018.The others also will leave the heliosphere (see notes 1) and reach interstellar space in a

Fact Sheet

Triton, the largest of the moons of Neptune, was shown to be not only the most intriguing satellite of the Neptunian system, but one of the most interesting in all the solar system. It shows evidence of a remarkable geologic history, and Voyager 2 images showed active geyser-like eruptions spewing invisible nitrogen gas and dark dust particles
