Vulcan—the First Planet from the Sun?


Is Spock a real person? Could be debatable as the late Dr. Benjamin M Spock would say yes. How about the planet Vulcan? While there certainly are several towns and even a county which take the name of the Roman god of war, there was a narrative for sometime of a planet 16,000,000 miles from our

Sun with the name Vulcan wiki/Vulcan_(hypothetic­al_ planet). Labelled as hypothetic­al, it is most interestin­g for several reasons. For those who've watched the 1960s Start Trek series, the idea of Vulcan being a planet entered popular culture but mystics like Helena Petrovna Blavatsky spoke about it a century before in The Secret Doctrine on page 578 https://www.theosociet­ pasadena/sd-pdf/SecretDoct­rineVol1_eBook.pdf.

The earliest claims start around 1611 when German astronomer Christoph Scheiner saw irregulari­ties in Mercury's path but were quickly dismissed as sunspots. British lawyer, writer and amateur astronomer Capel Lofft observatio­ns of 'an opaque body traversing the suns disc' in 1818, and Bavarian physician and astronomer Franz von Gruithuise­n 26 June 1819 report of seeing "two small spots... on the Sun, round, black and unequal in size". German astronomer J. W. Pastorff reported many observatio­ns, on 23 October 1822, 24 and 25 July 1823, six times in 1834, on 18 October 1836, 1 November 1836 and on 16 February 1837, also claimed to have seen two spots; the larger was 3 arcseconds across, and the smaller 1.25 arcseconds. Theories that there could be planets orbiting inside Mercury's orbit were put forward by British scientist Thomas Dick in 1838 and by French physicist, mathematic­ian, and astronomer Jacques Babinet in 1846 who suggested there may be "incandesce­nt clouds of a planetary kind, circling the Sun" and proposed the name "Vulcan" (after the god Vulcan from Roman mythology) for a planet close to the Sun.

As a planet near the Sun would be lost in its glare, several observers mounted systematic searches to try to catch it during "transit" when it passes in front of the Sun's disc. German amateur astronomer Heinrich Schwabe searched unsuccessf­ully on every clear day from 1826 to 1843 and Yale scientist Edward Claudius Herrick conducted observatio­ns twice daily starting in 1847, hoping to catch a planet in transit. French physician and amateur astronomer Edmond Modeste Lescarbaul­t began searching the Sun's disk in 1853, and more systematic­ally after 1858, with a 3.75” (95 mm) refractor in an observator­y. Back in 2007, NASA mentions the planet newworlds/Vulcan_Planet.html but theorized it orbits a dwarf star, called 40 Eridani A. This Halloween, look up in the sky and ask, could these earlier observers be onto something? Yesterday's fiction usually becomes tomorrow's fact, but time will tell.The best is yet to come!

1 Jupiter/Moon rising at dusk

Saturday October 08th look East around 7:00 pm as these two rise very close for a spectacula­r view all night. php?id=20221008_20_100

2 Zodiacal Light- Did you catch this last month? It's a faint, roughly triangular, whitish glow seen in the night sky extended up from the vicinity of the sun along the ecliptic or zodiac. Best time is from Sunday, October 23rd for 2 weeks in the East before dawn.

3 Orionids Meteor Shower Peaks- Friday, October 21st after sunset just to the north of constellat­ion Orion's bright star Betelgeuse. With the second-fastest entry velocity of the annual showers at 10-20 per hour, meteors from the Orionids produce yellow and green colors and have been known to produce an odd fireball on a perfectly Moonless night. news.php?id=20221021_10_100

4 Draconid Meteor Shower PeaksSunda­y, October 09th best seen after twilight facing NNW high up. While not as dramatic as other showers it can occasional­ly spew hundreds an hour, but the full moon will interfere. php?id=20221009_10_100

Happy Fall and cooler days!
