Hello, Pluto! In July of 2015, a spacecraft named New Horizons arrived at Pluto after a long journey. It took amazing pictures of this dwarf planet and will continue to study other objects in the Kuiper Belt from 2018 to 2022. Find out more about Pluto. Make a comet on a stick!

Over the past 60 years, humans have begun to explore our solar system in earnest. From the first launches in the late 1950s until today, we''ve sent probes, orbiters, landers, and even rovers (like NASA''s Perseverance Rover that touched down on Mars in February 2021) to every planet in our solar system.
A multiisotope (O, Si, Mg) characterization of AOAs is performed to constrain the conditions under which they condensed and the information they bear on the structure and evolution of the Solar protoplanetary disk. Significance Combined O, Si, Mg isotopic measurements of amoeboid olivine aggregates allow the individual condensation

Homogeneity of 26Al is also suggested by precise in-situ Al-Mg measurements of
A real-time, in-browser, interactive simulation of our solar system. Observe what the solar system will look like at any given point in time.
Our solar system consists of our star, the Sun, and everything bound to it by gravity – the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; dwarf
The solar system is a pretty busy place. It''s got all kinds of planets, moons, asteroids, and comets zipping around our Sun. But how did this busy stellar neighborhood come to be? Our story starts about 4.6
The solar system, as we know it today, is about 4.5 billion years old. It is widely believed that it was essentially completed 100 million years after the formation of

The order and arrangement of the planets and other bodies in our solar system is due to the way the solar system formed. Nearest to the Sun, only rocky material could
In our Solar System, there are eight planets. The planets in order from the Sun based on their distance are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. The planets of our Solar System are listed based on their distance from the Sun. There are, of course, the dwarf planets Ceres, Pluto, Haumea, Makemake, and
First Solar is a leading global provider of comprehensive photovoltaic ("PV") solar solutions which use its advanced module and system technology. The Company''s integrated power plant solutions deliver an economically attractive alternative to fossil-fuel electricity generation today. From raw material sourcing through end-of-life module recycling, First
Our Solar System. Our solar system is made up of a star—the Sun—eight planets, 146 moons, a bunch of comets, asteroids and space rocks, ice, and several dwarf planets, such as Pluto. The eight planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Mercury is closest to the Sun. Neptune is the
Ceres. Ceres is the smallest dwarf planet with an equatorial diameter of about 599 miles (about 964 kilometers). Ceres is about 1/13 the width of Earth. The closest dwarf planet to the Sun, and the only dwarf planet in the inner solar system, Ceres orbits the Sun from an average distance of 257 million miles (413 million kilometers) Ceres is about 2.8 times
The age of the Solar System is defined by the formation of the first solid grains in the solar nebula. Pb–Pb age dating of these solids, which were later trapped in a meteorite, indicates that
In Depth. The Sun is a 4.5 billion-year-old yellow dwarf star – a hot glowing ball of hydrogen and helium – at the center of our solar system. It''s about 93 million miles (150 million kilometers) from Earth and it''s our solar system''s only star. Without the Sun''s energy, life as we know it could not exist on our home planet.
and the farthest! 47. The ice giant Neptune is the farthest of all the planets in our solar system from the Sun. The blue gas planet is about 58 times the size of Earth, with 17 times the mass. Because it is so far away from Earth, the planet can only be seen with the help of a strong telescope. 48.

Significance. Combined O, Si, Mg isotopic measurements of amoeboid olivine aggregates allow the individual condensation timescales of a typical set of the first Solar System solids to be estimated. Our results indicate formation over days or weeks, much faster than could be inferred from the secular evolution of the Solar protoplanetary

In 1734 Swedish philosopher Emanuel Swedenborg proposed a model for the solar system''s origin in which a shell of material around the Sun broke into small pieces that formed the planets. This idea of the solar system
The First Exoplanet Discoveries The first solar system found outside our own did not involve a main sequence star like our own, but a pulsar. Unexpected to say the least. Since then we have found thousands of exoplanets (and in every sort of star system imaginable), and we continue to narrow in on smaller and []

There is evidence that the formation of the Solar System began about 4.6 billion years ago with the gravitational collapse of a small part of a giant molecular cloud. Most of the collapsing mass collected in the center, forming the Sun, while the rest flattened into a protoplanetary disk out of which the planets, moons, asteroids, and other small Solar System bodies formed.
The Space Race Takes Solar to New Heights. In 1958, the U.S. launched Vanguard 1, the first solar-powered satellite. Its radically new power system, made up of six solar panels, enabled it to remain in orbit for over six years. Other solar-powered satellites followed, including NASA''s Nimbus and Soviet spacecraft like Sputnik 3.
