A BRIFE INVESTIGATION ON COMETS ORIGIN AND FORMATION Kaveh Mozafari

Comets Tail Straight Bluish or plasma tail – Caused by: Complex interaction between the comet and – Solar wind – Solar magnetic field – The blue color is due to CO+ which Absorbs ultraviolet and remit most Energy at 4200Å Yellowish Dust – Caused by: Solar wind Radiation pressure of the Sun

Short Period Comets are coming from Kuiper Belt (30AU) Long period comets are coming from the spherically oriented Oort cloud 3000 to AU

Kuiper Belt direct evidence

Oort Cloud Oort Cloud has two main devisions: 1.The Inner Cloud – 30000AU to 20000AU – This Section has slightly more objects near the ecliptic 2.The Outer Cloud – From to – Almost spherical – Move in two way Neptune or stars passing

Planetesimal and the way solar system created the comets
