Pluto...



This is my passion when i was in primary school..but the interest decline along with time..but suddenly cam kembali berminat pulak nk bace the article about planet2 nih.....

--------------------------------------------------------------------------------

On 24 August 2006, Astronomers had declared that Pluto is no longer a planet.It makes our solar system occupied with only just 8 planets. Since it was discovered in 1930 until 2006, Pluto is the ninth and the smallest planet in the solar system.

The astronomist claims that it doesnt have the characteristics of a planet. After debating the issue for a period of time, International Astronomical Union (Kesatuan Astronomi Antarabangsa) voted Pluto out from the solar system.(cam AF la pulak main vote2 nih..)

Ianya akan diklasifikasikan semula dalam satu kategori baru iaitu "planet kerdil".Carol Holmberf, Pengarah Fort Myers Planetarium menerangkan bahawa debat bermula apabila saintis menemui seketul batu yang lebih besar dari Pluto dalam orbit yang sama.Dia berkata lagi, sebelum keputusan diambil, planet diistilahkan sebagai apa sahaja yang terapung di sekeliling matahari.

Pendefinisian baru planet 2006
The IAU...resolves that planets and other bodies in our Solar System be defined into three distinct categories in the following way:

(1) A "planet" is a celestial body that:
(a) is in orbit around the Sun,
(b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and
(c) has cleared the neighbourhood around its orbit.

(2) A "dwarf planet" is a celestial body that:
(a) is in orbit around the Sun,
(b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape ,
(c) has not cleared the neighbourhood around its orbit, and
(d) is not a satellite.

(3) All other objects except satellites orbiting the Sun shall be referred to collectively as "Small Solar System Bodies".





















The IAU further resolves:Pluto is a "dwarf planet" by the above definition and is recognized as the prototype of a new category of trans-Neptunian objects.

Walaupun begitu, NASA masih meneruskan pelannya untuk ke Pluto. Kapal angkasa The New Horizons berlepas dari Florida pada Januari lalu dan akan tiba di Pluto dalam masa lapan tahun lagi. Kapal sebesar piano itu merupakan pesawat pertama yang akan melawat planet kerdil itu.

hehe...so damn interesting rite??luv it..
