 * 1. Swiss scientists Michel Mayor and Didier Queloz discovered 51 Pegasi b, the first extrasolar planet.

2. The [|exoplanet]'s discovery was announced on October 6, 1995, using the [|radial velocity method] and a [|spectrograph].

3. 51 Pegasi B is about 51 light years away. Its mass is a little more than our sun's mass with a solar mass of 1.06. This planet is a large gas planet. It is a superheated gas planet with strong winds.

4. The first extra solar planet discovered was found from the radial velocity method. In 2009 a close contestant for the next earth like planet was found. It has water, reasonable temperatures and a similar mass to earth. However it's very dense and almost completely covered with water. Currently there have been over 500 extrasolar planets found.

5. I think in time we will continue to find more and more extrasolar planets. The only obstacle i think we will have is money. Not many people are willing to pay astronomers to find extrasolar planets so we will have a limited number of astronomers studying this. Also for this reason we will not have many engineers developing better telescopes and other equipment to find extrasolar planets. It is only a matter of time until we find an earth-like planet and possibly even alien life.

It is made up from minerals such as __hornblende__

It is also made up from the mineral __pyroxene__

It is also made up of a little bit of __quartz__

Diorite forms deep in the earth's crust from cooling magma - just like granite. But, the magma does not contain a lot of quartz or the light colored minerals that make up the granite. Instead it contains only dark colored minerals.




 * **Magnitude** || The magnitude of an earthquake is a measure of the amount of energy released. Each earthquake has a unique magnitude assigned to it. This is based on the amplitude of seismic waves measured at a number of seismograph sites, after being corrected for distance from the earthquake.

The New Zealand Earthquake was recorded at a 6.3 on the Richter scale.

There are many different magnitudes of earthquakes. The higher the magitude, the more energy released from the epicenter. By looking at this chart we can see that this earthquake was pretty strong. Every magnitude || **Magnitude** || **Earthquake Effects** || **Estimated Number** The damage from the New Zealand Earthquake will cost around $15.1 Billion. The death toll in New Zealand is around 150 with hundreds more trapped in buildings. ||
 * Each Year** ||
 * 2.5 or less || Usually not felt, but can be recorded by seismograph. || 900,000 ||
 * 2.5 to 5.4 || Often felt, but only causes minor damage. || 30,000 ||
 * 5.5 to 6.0 || Slight damage to buildings and other structures. || 500 ||
 * 6.1 to 6.9 || May cause a lot of damage in very populated areas. || 100 ||
 * 7.0 to 7.9 || Major earthquake. Serious damage. || 20 ||
 * 8.0 or greater || Great earthquake. Can totally destroy communities near the epicenter. || One every 5 to 10 years ||  ||
 * **Impact** || Many buildings have been destroyed and the town of Christchurch is now in ruins.
 * **Cause** || The Alpine fault lies right there and it can often produce fairly strong earthquakes. ||
