The temperature on a comet will vary by its position in its orbit. The part exposed to direct sunlight can easily reach 100°C or higher when close to the Sun. When a comet is at its farthest from the Sun, its temperature falls to as low as 4 K (-269°C), the effective temperature of outer space.
The temperature on a comet near Earth's orbit was measured by a NASA probe. The surface temperature on the Sun side was up to 50°C (122°F), while the side facing away was still -30°C to -80°C, indicating that the heat there had re-radiated into space, or been lost in the release of gas and dust. When the comet Ikeya-Seki curved around the sun last October, many astargazer's camera was focused on its fiery trail. But two California Institute of Technology researchers were deter mined to record far more than mere surface glow. And the Astrophysical Journal last week reported remarkable success. Eric Becklin, a graduate student in physics, and James Westphal, a senior research fellow in planetary science, not only obtained the first temperature measurements ever made of a comet, they also gained valuable insight into a comet's composition and behavior.
After fitting a 24-inch telescope with a sensitive infra-red detector, the Caltech scientists trained it on the comet for 19 days during its passage around the sun. Their first temperature measurement-700° F.-was made when Ikeya-Seki came within 45 million miles of the sun and heated up enough for its infra-red emissions to be picked up on earth. As the comet raced closer to the sun, its temperature climbed gradually, reaching 1,200° F. about 20 million miles from the solar surface. Then the comet's emissions were blotted out by the sun's own fierce radiation. On the return leg of its journey, Ikeya-Seki displayed identical temperature variations, dropping from 1,200° F. at 20 million miles to 700° F. at 45 million miles.

What is the temperature on planet Biyo?
The temperature on 13241 Biyo, which is an asteroid, is a few tens of degrees Kelvin.
Is the temperature of the outer core higher OR lower than its melting point?
The outer core is liquid. Its pressure is low enough and its temperature high enough for it to melt. The inner core is solid. Both its pressure and temperature are higher than the outer core, but the increased pressure overwhelms the increased temperature, keeping the inner core from melting.
What your temperature supposed to be?
Your core body temperature is supposed to be 98.6 degrees on average.
Why do you measure the core temperature of a patient?
Measuring the core temperature of a patient is important because it provides an accurate assessment of the body's internal temperature, which can help in diagnosing and monitoring conditions such as infections, heat stroke, hypothermia, and hormonal imbalances. Core temperature measurement is more reliable than surface temperature and helps guide appropriate treatment.
How does temperature change from the crust of earth to the core?
The temperature increases as you move from the Earth's crust towards the core. The temperature in the crust varies depending on factors such as depth and geothermal gradient, while the core's temperature reaches over 5000 degrees Celsius due to the immense pressure and radioactive decay.
What is a temperature on a asteroid?
A typical asteroid is -100 F or -73 C.
Stony meteorite metal?
chunks of the core of a larger asteroid that was shattered by a collision.
What is the core's temperature in Fahrenheit?
The core's temperature is approximately 1500C and in Fahrenheit its 45699F

What should your body core temperature be?
98.6F is the normal body core temperature in humans.
Does the sun effect the earth's core temperature?
No. Earth's core temperature is determined by processes within the Earth.
Differentiate between the core temperature and shell temperature?
Core temperature refers to the internal temperature of the body, typically measured in areas like the rectum or the esophagus. Shell temperature, on the other hand, refers to the temperature of the skin on the body's surface. Core temperature reflects the body's overall internal temperature, while shell temperature can be influenced by external factors like clothing or the environment.
Is the temperature of the outer core higher OR lower than its melting point?
The outer core is liquid. Its pressure is low enough and its temperature high enough for it to melt. The inner core is solid. Both its pressure and temperature are higher than the outer core, but the increased pressure overwhelms the increased temperature, keeping the inner core from melting.
What is the temperature of the inner core of the earth in kelvin?
The temperature of the Earth's inner core is estimated to be around 6000 kelvin.
What is the difference between core and shell temperature?
The core temperature is heat inside the body whereas the shell is the outer, knowingly the skin layer temperature
