The Solar System

It is our Moon.

In March of 1989 a large sunspot appeared and it then sent off a huge solar flare. A few days later a second solar flare erupted. This one came towards Earth and created spectacular Aurora Borealis sightings and created major electrical problems in Canada.

No, everything with a mass has gravity. That's why the planets orbit the sun. That's why moons orbit planets. The asteroid belt etc. If you drop something heavy on the moon, it'll still fall to the ground, this proves that there is gravity on the moon. The Mars rover is still on Mars, it hasn't

Graffias the name for some stars forming the head of the scorpion in the constellations of Scorpius. The main star(s) in this group is/are called Beta Scorpii and is about 400 light years away from the Earth/Sun.

A bit inside the orbit of Mercury, at about 0.3 AU.

No. A sunspot is a slightly cooler area of the surface associated with magnetic disturbances within the Sun. The eruptions of gas are called prominences, and they are related to the phenomenon called solar flares.

I sneeze 75 times a day. The average human sneezes 4-5 times a day. (I work in a pepper factory during the week) and I have terrible pollen allergies (I work in a flower garden on weekends) I am allergic to cats and dogs and foster both. (I probably foster 20 families a month) My fostered cat always curls up on my shoulder and rubs her body on my face when I'm trying to sleep (Those days I sneeze probably close to a hundred) My fostered dog sits on my lap and lays his head on my face and starts licking my nose when I'm trying to watch TV (Those days I probably sneeze 85) I sneeze more with cats than dogs because cats have more fur. And you won't believe this, but my animals SHED. Shed all around my house. But they mostly like to shed on my bed. Everything in my house is covered in cat and dog fur. And worse my friends think It's FUNNY! They always try to make me sneeze even more.

The sun has rings (I think)

No. They are much greater.

Uranus was discovered by William Herschel on March 13, 1781, 229 years ago.

Neptune, however, was first observed on September 23, 1846, only 164 years ago.

Of course they had been in the solar system for a few billion years.

It's just that they weren't in our model of the solar system, until discovered.

Mercury: A little less than 88 days.

Venus: Almost 225 days.

Earth: Exactly 365.256363004 days.

Mars: Almost 687 days.

Jupiter: A little less that 4,333 days.

Saturn: Exactly 29.4571 years.

Uranus: Almost 84.323 years.

Neptune: Exactly 164.79 years.

Curious note:

Since Neptune was discovered, in 1846, it has not yet completed one single full orbit around the Sun.

In other words, since its discovery, for Neptune not ONE local year has passed by...

The Sun; planets; moons; dwarf planets; asteroids; meteoroids; interplanetary dust and gas; comets; solar wind...

The total solar eclipse observed from Cornwall occurred on August 11th, 1999.

Ganymede, which is Jupiter's largest moon. A robotic probe was launched there about 4 years ago equipped with a drill, which will hopefully be able to drill through the ice covering the planet's surface and extend a probe into the freezing murky depths of Ganymede's ocean, which might just possibly reveal some primitive marine life there!!

Neither Mercury nor Venus has any moons. The Earth has the Moon, and Mars has two moons, Phobos and Deimos.

It has to be eight words.

the year.

I think it is. Take a look at some pictures of Mimas; it looks pretty round to me.

The source of gravitational pull in our solar system is the combined mass of all the celestial bodies, primarily the Sun. Gravity is the force that attracts objects towards each other, and in our solar system, this force is what keeps planets, moons, asteroids, and other objects in orbit around the Sun.

The rest of the solar system orbits a star (the Sun) which stays at the centre.

To be precise, the whole solar system revolves around its center of mass.

The Sun has about 99.85% of the entire mass of the solar system.

So, its not surprising that the center of mass of the solar system is close to the surface of the Sun and that the Sun more or less stays at the center.

The wording of this question needs to be improved to understand what you mean.

Because the Earth was made from material that was orbiting the proto Sun.

1. There is no known life anywhere in our solar system except on Earth.
2. As currently defined our solar system only has 8 planets.

It all depends on just what do you mean by solar system.
We can't use miles or meters to measure the solar system since it is so large. We have to use astronomical units. 1 AU is the average distance from the Earth to the Sun, or approximately 150 million kilometers or 93 million miles. If you could drive your car at highway speeds, from the Sun all the way out to Pluto, it would take you more than 6,000 years to complete the trip.

The true size of the Solar System is defined by the reach of its gravity; how far away an object can
still be said to orbit the Sun.

In the furthest reaches of the Solar System is the Oort Cloud; a cloud of icy objects that could orbit the Sun to a distance of 100,000 astronomical units, or 1.87 light-years away.
The Sun’s gravity dominates local space out to a distance of about 2 light-years, or almost half the
distance from the Sun to the nearest star: Proxima Centauri. Believe it or not, any object within
this region would probably be orbiting the Sun, and can be thought to be a part of the Solar System.

At those distances, it would take you 19 million years to complete the journey in a car to the edge
of the Solar System.
