If you think you will be able to float around your house then you will be mistaken. BUT if you jump in the air at 9:47AM local time on January 4th 2014, it should take you about 3 seconds to land back on your feet instead of the usual 0.2 seconds.




So how long from 13,500? :o

Is it even real?

A mosquito on your skin has a greater gravitational pull on you than Jupiter does... You could have a hundred Jupiter's lined up on the other side of the sun and it would not have this effect. The sun would simply wobble a little more than usual (with the 100 jupiter scenario, the pluto behind jupiter scenario would not be measurable).

Oh well, plenty of Americans will fall for it :) ;)

Wasn't the part about having to 'jump into the air' to experience this enough of a hint? :P

I am into Physics. I will try to help.

Once in a while, there are alarmists who claimed that weird things are going to happen like planet aligment or, last year, the end of our civilisation in December 2012 according Maya's calender or whatever....

First, since all planets have their own period of revolution around the Sun, a perfect aligment is not going to happen soon. Combine the revolution period durations of the 8 planets and one can see that an alignment of them all has very little chance to be seen in the next thousands years.

Second, gravitation decreases proportionally to the square of the distance which means that planets are so far away that their gravitational pull on the Earth is minute.
The Sun gravitation (Earth and Sun system) is strong due to the enormous mass of the Sun. That makes the Earth (and planets) orbiting around the Sun. The Sun itself is responsible for more than 99% of the entire mass of the solar system which means that planets influence is about nothing. However, nearby planets influence each other by slightly modifying their trajectory.
The only enligment which has a measurable effect on the Earth is when the Sun and the Moon are in line with the Earth (twice a month at the new Moon and the full Moon), that makes tides being bigger (high sea).
Learn from others mistakes, you will never live long enough to make them all.

This one's been around a while... like over 35 years ;)

From Wikipedia:
"The Jovian–Plutonian gravitational effect, a hoax phenomenon stated to cause a noticeable short-term reduction in gravity on Earth, was an invention for April Fools' Day by the English astronomer Patrick Moore broadcast on BBC Radio 2 on 1 April 1976."

And of course the joke is that Pluto is both utterly minute and phenomenally far away.

If it could have a noticeable effect then every planet or asteroid would be throwing us all over the place each time it passed.
Do you want to have an ideagasm?

Sometime Pluto is nearer from us than Neptune due to its orbit partially inside the Neptune one. OTOH Pluto has been declassified as a planet. It is now a "minor" planet like Sedna.
