In Depth | Sun ? NASA Solar System Exploration
13 Apr 2026 at 5:47am
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.

The Sun is the star at the heart of our solar system. Its gravity holds the solar system together, keeping everything ? from the biggest planets to the smallest bits of debris ? in its orbit.
In Depth | Our Solar System ? NASA Solar System Exploration
13 Apr 2026 at 2:12am
The planetary system we call home is located in an outer spiral arm of the Milky Way galaxy. 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 planets such as Pluto; dozens of moons; and millions of asteroids, comets, and meteoroids. Beyond our own solar system, there ...

In Depth | Earth's Moon ? NASA Solar System Exploration
11 Apr 2026 at 6:14pm
The brightest and largest object in our night sky, the Moon makes Earth a more livable planet by moderating our home planet's wobble on its axis, leading to a relatively stable climate. It also causes tides, creating a rhythm that has guided humans for thousands of years. The Moon was likely formed after a Mars-sized body collided with Earth several billion years ago. Earth's Moon is the only ...
In Depth | Kuiper Belt ? NASA Solar System Exploration
9 Apr 2026 at 7:42pm
Size and Distance The Kuiper Belt is one of the largest structures in our solar system ? others being the Oort Cloud, the heliosphere, and the magnetosphere of Jupiter. Its overall shape is like a puffed-up disk or donut. Its inner edge begins at the orbit of Neptune, at about 30 AU from the Sun. (1 AU, or astronomical unit, is the distance from Earth to the Sun.) The inner, main region of ...

Jupiter is the fifth planet from the Sun, and the largest in the solar system ? more than twice as massive as the other planets combined.

Kuiper Belt and Oort Cloud - NASA Solar System Exploration
12 Apr 2026 at 12:04am
The Kuiper Belt should not be confused with the Oort Cloud, which is a thousand times more distant. In 1950, astronomer Jan Oort proposed that certain comets come from a vast, extremely distant spherical shell of icy bodies surrounding the solar system. This giant swarm of objects, now named the Oort Cloud, occupies space at a distance between 5,000 and 100,000 astronomical units. No objects ...
