An AccoUNT of the DIscovERY of ANOTHER NEW PLANET, 
by DR. OLBERS, of BREMEN. 
On the 28th of March 1802, Dr. Olbers, accidentally looking at the flar No. 20, 
in the northern wing of the Virgin, near which he-had redifcovered Ceres Ferdinan- 
dea, on the firft of January laft, to nis great furprife he faw a far of 7th magnitude, 
formigg an equilateral triangle with No. rg and 20, of the Virgin; wiich he was 
perfuaded had not been vifible there at that time; by which circumftance, and by 
tracing its mction, he found it was another new planet. It appeared to him, with 
his Dolland’s teleicope, perfectly refembling Ceres, without either atmofphere or 
nebula, and not to be diftinguifhed from a fixed ftar. _Suppofing it to be a pianet 
moving 10 a Circular orbit, they have calculated its diftance from the fun to be twice 
aud one tenth our diftance from the fun, and its periodic time, about three years. 
T he inclination of its orbit to the eliptic muft be very confiderable, as on the 12th of 
this month, its obferved latitude was nearly 16°. Dr. Olbers has named it Pallas.

Further Particulars of p1azz1’s New Planet, called Ceres Ferdinandea. 
THE Planet was in oppofition to the fun on the 17th of March. It was then 
near its northern limit of latitude, and about 30° paft its perihelium; and was 
nearly in as favourable a pofition for being feen, as it ever will be. Taking its cor- 
rect apparent diameter to be a fecond and a half, its real ciameter will be about 
one-feventh of that of the earth, or half that of the moon. Its apparent place in the 
heavens, from April 30, to June 29, has been computed by Dr. Gauls, from his 
elements, as follows, for midnight in the meridian of Seeberg, or Saxe-gotha :

Dr. Gaufs, to whom we are indebted for his calculations, by whieh the planet was 
re-difcovered by Baron Zach-and Dr. Olbers, is a young man, of Brunfwick, of 22 _ 
years cf age, of extraordinary mathematical genius, who was taught mathematics 
by Zimmerman, at the expence of the Duke of Brunfwick, and had read. Newton’s 
Principia through at eighteen. He has publithed a very learned treatife oa the higher 
parts of arichinetic, in a very perfpicuous ftile, in Latin; which he has dedicated te _ 
his patron the Duke of Brnafwick. . |
