What is the sun and the celestial objects bound to it by gravity?

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.

What are the 5 regions of the solar system?

In broad terms, the charted regions of the Solar System consist of the Sun, four terrestrial inner planets, an asteroid belt composed of small rocky bodies, four gas giant outer planets, and a second belt, called the Kuiper belt, composed of icy objects.

What are the 2 regions of the solar system?

There are two main regions: the inner region and the outer region of the solar system. The inner region reaches up to Mars, and everything beyond Mars, even the Kuiper Belt and the Oort Cloud are in the outer region.

What are the 4 types of bodies in the solar system?

The small bodies in the solar system include comets, asteroids, the objects in the Kuiper Belt and the Oort cloud, small planetary satellites, Triton, Pluto, Charon, and interplanetary dust.

What is the smallest celestial body?

Ceres

What is the true color of earth?

Explanation: Here are the true colors of planet Earth. Blue oceans dominate our world, while areas of green forest, brown mountains, tan desert, and white ice are also prominent. Oceans appear blue not only because water itself is blue but also because seawater frequently scatters light from a blue sky.

Who discovered the Earth?

Eratosthenes

What is the temperature of sun?
